Customer 50 (rude and dumb)

Customer came in to upgrade her phone from an iPhone 6 to an iPhone 7. No problem. She wants the biggest memory 256gb because her 128gb is full no problem. I inform her we can't transfer 128gb of data because apple doesn't let us use iTunes so we don't have it and our other machines take around 20-30 min per GB and the machines reset every night so they won't transfer overnight. She asks me what I mean.... So I reword it. You have to much data to transfer on our machine. And she said your repeating yourself. I'm like.... I know because you didn't get it the first time so I said it again just in a simple and dumb person way...... Of course I didn't tell her that part because I'm suppose to be professional. The she gets pissy but try to hide it saying she has a conference and has to speak for the president and this and that. Making herself sound super important. Come to find out all she's really doing based on the little pieces of info I picked up is speaking in front of less than a dozen people at her job which is someone else's small business. Anyway, so then she asks me to fix her blackberry..... Yes blackberry nearing the end of 2016..... Reason being she only keeps her blackberry around because when she got her iPhone 2 years ago we couldn't transfer all the information off of it. Which is true because our machines hate blackberry's and in fact only half of our technicians even work on blackberrys because they are difficult and obsolete so their is no point in learning how to fix something we don't even sell and haven't for like at least 3 years. So I inform her of the little we can do and she asks. Ok well can I be reimbursed since it's not working..... Really .... You had it for at least 4 years based on what information you gave me and you want us to reimburse you for it malfunctioning when your replacing it's replacement? Your out of your mind. Then she asks me if theirs an upgrade to it. I tell her we don't have an new BlackBerry but you can upgrade it to any phone you choose around the store but we still won't be able to transfer anything off of it more then contacts. Then she gets pissy and starts saying I'm missing her point and that she only wants to replace or keep it because she has things on it we couldn't transfer 2 years ago. And we still can't now. I'm like no..... I didn't miss the point.... Your dumbass is trying to catch me in misinformation so that you can call over my manager and tell him I said something incorrect and now we have to do it because I said it. People pull that shit all the freaken time. And I could say anything in the world but that still wouldn't change the fact our machine can not transfer your notes. Bookmarks. And other bullshit off your BlackBerry. Some people love to accuse people in retail/sales of being ignorant but quite often I notice from my job customers just never understand what you say and they assume a perfect world for them and assume they are always right.
