Shocked at the service of Autopage

I upgraded my phone 7October 2015. My upgrade was due 10October 14. Every month i have payed the account. Every morning i receive a sms stating that my account is R0. Januarie '15 I receive an sms from Autopage that my account is due R7800 and something. I phoned Kim, @ Autopage Benoni, where i did the upgrade. She said she will sort it out seeing that they never put me on the new contract! Laste week i received a sms from Autopage saying they are working on my request. Today i get a phone call from Trudi at Autopage saying my account is now R11 000!!! The line has been suspended for a month! Trudi also tells me that my contract was only due January '15. I phoned Autopage June last year when it was already 24months and they told me i can upgrade 10 October! Due to people not doing their job correctly i have a R11 000 bill. I am shocked in the service i received from Autopage!!!!!!
