Bad service

On the 4th of September I walked into the Tygervalley store to have my phone repaired, they told me its gonna cost /- R3000 to fix so I said but then I might as well take another phone. I was referred to the sales guy, Yumna Moosa. He sold me a new phone contract under the impression I can transfer my data and airtime to my existing line. Because what would I do with 2 contracts and 1 phone? I have sent in a complaints letter to Verna she referred me to Chantal the CRM @ Tygervalley. It is now 3 months down the line and no solution has been made. Every time empty promises are being made and every time I am being referred to someone else but till thus far nobody has come up with a solution for me. It was not my fault that their staff was not properly trained. I prefer this contract to be cancelled. I will return the phone no problem, but I cannot pay for something which I cannot use.
