UPGRADE PROBLEMS

I was contacted by a consultant of Autopage in the beginning of May 2015 regarding my upgrade. I have been viable for upgrade since February 2015 but never had the time and therefor only agreed to the upgrade because I knew that I could upgrade and my previous contract has actually lapsed. I had a Blackberry, with BIS so my charges each month were never more than R300 pm. I chose the most affordable option for me available which were a Sony with 75 min of call time, 200 sms and 200MB each month. At the end of May, when I only activated the phone on 17 May 2015 I received an account of ? R1700.00!!! I contacted Autopage immediately and requested an explanation. Up to date I have never received any feedback. When the money was deducted from my bank account I contacted Autopage and demanded an answer, which was : I am still on my old contract, I can only \migrate"on 23 JULY 2015!!!! I know received another account of R1000.00 - UNACCEPTABLE !! And still no response from Autopage. MY account for the past 2 months have been more than what I paid the last TWO YEARS !!!!"""
