VODACOM DOES'ST WANT TO CANCEL MY CONTRACT AFTER I HAVE PAID THE SETTLEMENT AMOUNT. PLEASE HELP ME TO CANCEL THIS CONTRACT.

I am struggling to cancel my contract with Vodadom. I have the settlement figure which I have signed and paid. I have attached the required document send send it to ***. I have called several times and e-mailed more than 20 times, my e-mail is being read but I don't get confirmation that my account will be cancelled. Instead I get a message to say that it's unsuccessful. I have attached the relevant documents but I am not getting the reference number. When I call, the call centre I am being directed to retentions department. I don't want ANY CONTRACT ANYMORE. I WANT TO CANCEL THIS ONE AS I NO LONGER NEED VODACOM SERVICES. HOW MANY TIMES MUST I FORWARD THE E-MAIL?? THIS IS REALLY FRUSTRATING. I AM SPENDING SO MUCH TIME REPEATING ONE AND THE SAME THING. PLEASE CANCEL MY CONTRACT.
