Managers 2 (Bad)

Sorry i know i'm ranting again

This happened at my last job, i was in a location selling all the major wireless carriers. We were very not well known and in the time i was there (over 2 years!) we would see MAYBE 3 customers a month. Which was not a bad gig, the pay sucked making minimum wage with a commission potential of about a grand a month and i would literally get to sit there and play on my phone and wait until i had a customer which would be again 3 times a month. They set my goal at 30 people per month, 30, ill say that again, i would see maybe 3 per month and i would have a goal of 30. That $1,000 commission turned into around $20 per month, great..... So 4 months before i left a different company bought out our contract and offered to take all previous employees in and give them a very tiny pay bump (about 50 cents an hour). I accepted because i was young, in college and didn't have anything better. Days after this we had fraudulent activity in the store and we knew it, i will get back to that in a min. My manager did not accept this transfer so i was the only person at my location for over a month and i answered to my district manager. I gave him my collage schedule which was only 2 days a week. He had the nerve to schedule me open to close all 7 days a week and scheduled me over 70 hours a week. I was a full time student i could not do that but you know what i could use the extra money so i still did around 55 hours a week 5 days when i could and he threatened to fire me multiple times for this and even told me i would have to skip class to come to work and even called me while i was in class to tell me to come to work. The nerve on this guy, to make it worse that fraud activity would buy around 40 phones a month from me, which was great racking in large paychecks but i didn't want money that why. The 2nd time i seen them and realized it was fraud i turned them down and informed my district manager. He told me he did not care and wanted me to sell anyway because it did not matter if the wireless carriers got their monthly payments or not what mattered is that we sold the phone so they are required to pay us no matter what. I asked him if hes sure because this is immoral and he again threatened to fire me if he found out i was declining them again. So for the next 4 months i sold to them, hell they even gave me tips in quantities of $100 at a time for making it quick and easy. I know its wrong but they are not giving me a choice but to sell to them. They hired me a manager finally after a month and he was cool, great guy and we agreed on a lot even played games together online. They hired me a coworker to, nice girl,easy going and did everything she could. I trained her, and found out later she was barely old enough to work, no past job experience, just out of high school. I just finished an associates degree, had previous job experience and even trained my manager and they paid her more! I was pissed when i found this out, its not her fault we got along great and she even felt bad of this fact. I brought up this to my district manager and asked for a raise and he threatened to fire me again. So i dealt with this crap and my girlfriend at this time (long distance) was coming to visit, i planed out a vacation before the company contract buyout. Requested 2 weeks off and spent over $3,000 on this visit to make it the best for her i could. The time came and he told me the vacation i got approved for he wants me working during it. No, not going to happen this was the last straw. 3 weeks prior i told him you have 1 week to decide what your going to do, i will either get these 2 weeks off and come back to work after because i used no vacation time and had plenty saved up and it was already approved or you can consider that my 2 weeks notice when that day comes. So 2 weeks before the vacation he told me i;m working, i said ok i'm quitting, so you have me for 2 weeks then i quit here is my notice and i will email it to you as well and CC myself. I sent it and he called me up and said he does not approve my 2 weeks notice. What? I'm sorry? Your telling me i'm not allowed to quit? Who the hell do you think you are, i sent my email and that is that i am quitting my last day will be this day. So i quit, had my vacation and it was great. Unfortunately i failed one of my classes because although i took that time off and planned it in advance they scheduled multiple mandatory tests during that time that i could not make, or make up and they did it only a week prior. Back to my work, after the vacation which he called me every day during to leave a voicemail telling me i'm a no call no show at work. Finally the vacation was over and my girlfriend at the time (who is now my wife) went home. He called the next day i answered, he told me i was a no call no show for 2 weeks and had to come in that day to work. I told him i quit and i would resend him the email if he wants, he told me i'm fired for not showing up, i told him i had already quit screw off and don't ever call me again. Let me know what you think, was he right to fire me? Was i right for quitting? How would you have handled the fraud? Comment below.
