ybuy cricket wireless don't trust ybuy casa grande Arizona

 I went to cricket wireless to buy a new phone. I was covered by ybuy. I did my monthly payments in 3 months but they kept taking out my money twice a month. When I thought I had finished my payments, I get a text saying I still owe them money. I checked my account I see a balance of 645.00 I'm like WTF!!!!! Is going on. I called Ybuy and the lady was very hard to understand but she said their was late payments and the 645.00 was from all the late payments. I told her ybuy was doing audio pay it's not my fault. She said half of the payments wasn't audio pay. I was pissed off because she said I have 90days to pay if not they will kept charging me. How the f*** am I suppose to 645.00 In 90days the galaxy 5 phone is not worth paying double the price. How can a company rip off people like this. How do they sleep at night knowing they are steeling people's money..
