CELL C's PATHETIC CUSTOMER SERVICE!!

I received a call from one of their sales agents informing me that I am due an upgrade, of which i found strange as I am only due an upgrade in November, non the less the sales agent sold me some **** and bull story of how I have been such a good customer of Cell C's hence why i am getting the upgrade now. None the less, i opted for a phone of choice which was delivered to me only to find that when i activated the Sim card it was not an upgrade but in fact a new line. I then immediately requested that the handset be collected as I was given the phone believing it to be my upgrade. The handset has since been returned and approved for cancellation as the phone was returned in the same condition it was received. I have now been waiting for the contract to be cancelled for over 2 weeks now, each time i call to follow up, i get told that someone will get back to me, which never happens!My account has now been debited!I AM GETTING EXTREMELY IRATE WITH CELL C'S CALL CENTRE AGENTS AS NONE OF THEM HAS BEEN ABLE TO ASSIST NOR GET BACK TO ME!THE HANDSET HAS BEEN RETURNED, WHY THE HELL IS IT TAKING SO LONG FOR THE CONTRACT TO BE CANCELLED AND FOR ME TO BE REIMBURSED!!
