Incorrect contract taken out!!!!

Autopage knows nothing about customer service. I took out a Top Up contract with Naseeba from the Bluff store in December and a few months later was slapped with a bill of over R10 000. I called their call centre who said I need to go back to the store to find out what happened. I have been back to the store on numerous occasions and the last time this Naseeba girl logged a request and was supposed to get back to me. I am still waiting for her phone call. I had to call the call centre for feedback who said the store needs to phone them and ADMIT that they took out the wrong contract. However the store does not want to take a loss of R10 000, hence they are not interested in re-imbursing me. I found out from calling the call centre previously, that an open line contract was taken out. This Naseeba girl said some SUL was not activated on this contract, as it can be open line or have SUL. I cancelled my debit order months ago, so I could pay cash, but an amount of R 1042,10 was taken from my bank account. This is *******. You sent me final notice for non payment, but this account should be in credit with that R10 000 I paid. I want my money back and I WANT IT NOW!!!!
