Pathetic Service!

I am a very unhappy client of Autopage Somerset Mall. In 2014 I had a Blackberry phone that gave me problems in December and so I took it to the Autopage branch in Somerset Mall.<br> The manager said that he must send it in for repairs without any costs because of the 2-year warranty that I have on the phone. He told me that I was going to wait a very long time due to the holiday season to get it back from repairs, so he said that he can give me a refurbishing phone, at no cost, instead. I received the refurbishing phone and then I upgraded in February 2015. I received an invoice for April 2015 from Autopage's head office that I have to pay R1,228.82. I have not signed any documentation for the refurbishing phone as I was told there's no cost involve at all. I did not pay this amount and on the 16th of May 2015 my phone was suspended. On the 21st of May 2015 I've received a new invoice for the month of May, what a shock!! Now I am owing them R2,468.96. The Somerset West branch said I should contact head office to sort it out, however head office claims that the Somerset West branch should sort it out. It's been 2 months and no resolution has been found! Customer service are pathetic!
