Customer 19 (insane)

So a customer came in. They have 1 phone and their bill was over $600. So turns out she has not been paying it, so they told her in order to get it cut back on she needs to pay off the balance, so she paid around $450 and kept asking why it was still turned off. My coworker was working with her and kept saying its vecause you still owe money. So she request a manager, and we are all currently busy. So my coworker asks for a manager to help and my manager said she will ve out in a min and im busy and the other manager is going for lunch. So he leaves the store and she starts yelling across the room that its real great she wants a manager and hes leaving as she wants him. First off no one told her hes a manager, second hes on break and 3rd someone else is coming out to deal with you, yelling just shows us how unintelligent you are. So then she starts yelling at everyone else saying I see you all back there ignoring me, I need a manager now! One of you needs to come help me right now! Bitch you have someone helping you right now and someone else on the way calm down, stop yelling and stop being a bitch. So my manager gets there and were all listening and the customer said you need to turn my phone back on, which we cant do so she tells her we cant and asks why is it cut off. She said because theirs a balance and she owes us money. So my manager said ok then when its paid it will automatically be turned back on. She told my manager no, I want it on now this is your problem now fix it. My manager said well my phone is turned on soooo its not problem, you need to pay your bill. So she stormed out pissed.... well if she paid her bill she would have service...... so then she comes back in and starts yelling f you all you need to turn my phone back on this is bullshit. F this you need to fix this. Meanwhile my managers just like ok.. ok.. ok im calling the police now. Ok maam you can explain this to the police.  And when she called the police the customer bolted out the door like she was wanted. She knew what she was doing was wrong but she didnt care, some people do that to provoke the employee to attack them so they can sure the company but were not stupid we know your games....
