Customer Service

I became a customer with Sprint on the 2nd of Feburary and it was the worst decision I have ever made. I should have stayed with previous carrier. Customer service is not trained properly. First billed was billed incorrectly, I called and supervisor by the name of Trish told me she would issued a credit in the amount of 69.99 and that it would take 24 hours for my billed that was generated on the 5th of Feburary to reflect it. I was in the store on 2/23/15 and discovered that I was lied to. I had to call back and go thru the whole entire process again only to find out that I was only issued a credit of 42 something. While I was on the phone on 2/23 I spoke with a financial represenetative to extend my due date since I was used to paying my bill always on the 14th of each month, the customer service told me that he could only move me out to the 28th but I would have to call back on the 28th to have it extended out to the 14th. I called back on the 28th to find out that since I was a new customer and didn't have any pay history that I could not extend my payment out to the 14th and that I would have to pay half or the full amount on 2/28 or setup an automatic payment amount to be deducted out of my account. I was furious because of the miscommunication that I had received. Discovered on 2/28/15 that I had a credit on my account in the amount 264.38 after speaking with customer service representative 767471 (Cindy) and that there was no since to change my due date and to wait until my bill was generated on 3/5. Looked online today for my bill and there is no bill but CS is telling that my billed should be ready by 3/6/15...once again misinformed information. Also Sprint need not put people on the phone that can't speak fluent english it makes it very hard to understand them and to solve issues. If you want to keep a customer please escalate this complaint to the very top of the line.
