Red DISadvantage! Vodacom will not cancel my contract, continue to **********ly bill me!

I ********** -0 I have tried in vain to prematurely cancel my contract since the beginning of April 2017 and Vodacom continues to **********ly bill my account. The initial "failed attempt" occurred when the Call centre operator did not submit my request, which resulted in me incurring more fees from Vodacom. No surprise there. I went into their Pavilion branch, waited 20 - 30 minutes while staff were all laughing and failed to notice that I was even there so none bothered to call the next ticket! I asked the guy (who failed tell his fellow staff members that I had been waiting) that issues the ticket, what the hell I waiting for? before being directed to a consultant, and only to be told that they cannot submit a cancellation, but they would put a note on their system that would have someone contact me in 1 - 7 working days, despite being a Red Advantage customer then, I never received said call. So all in all wasting my time. I had to contact the call centre yet again around beginning May, this time a guy helped and, sent through a Premature cancellation quotation that stated I would pay R0.00 that I sent returned on 24 May 2017. They then cancelled the contract at end May, about 14 days later after my "supposed" last payment on 15 May 2017, but then sent me an invoice of R0.00, and a contradicting statement stating that I would have to pay a further full months fee! I have since been harassed by messages stating that I have been handed over for collection of fees, despite having cancelled the contract and fed false hopes that i would not have to pay a cent because they had messed up in the first place since April!!!!! I’ve tried to contact Vodacom numerous times thereafter to resolve this matter, and continue to tell me today that my contract is still active. I can't understand how?? When I have ported the cell number to Telkom and I am experiencing better service at much much lower rate. Yet Vodacom neglects to cancel my contract and continues to debit my account which is a direct infringement of the POPI Act. The call centre and in-store service is appalling, with regard to all call centre grievances, I have call recordings of which I will make available to any social media service and will make it my personal mission to voice and publicize my issue so as to prevent other people from having the same problem.
