Not solving problem with cancellation of contract

I upgraded my contract with Autopage. After being on Cell C for many ears and a customer of Autopage, I have been experiencing problems with Cell C reception in my area. I contacted Cell C and they have sent out an technician to investigate. They then said that they can't provide full service in my area anymore and they gave me a SD number to give to Autopage so that they cancel my contract from their side. I went to the Riverside Mall in Nelspruit to give back the device, but one of the sales agents informed me that they can't cancel it from their side as I took the contract out with Head office. He then poned to find out more for me. I was sitting right in front of him when he made a call to Lebalang Tema. According to the gentlemen who helped me I had 2 options, 1 to pay a settlement fee of R612.48 to cancel the contract. or no 2 to give them the SD number at Head office. Lebalang confirmed the amount. I have paid the amount into their account. But received an email from Lebalang that the settlement amount is over R2000. I have not yet reveiced an reply back.
