WAKE UP TELKOM MOBILE!!!!

I cancelled my contract with Telkom mobile after my 24 month period had passed as I no longer wished to have a contract for mobile data for my tablet. This was in OCTOBER 2015. I have yet to get any confirmation that this was done and AM STILL BEING BILLED PER MONTH (approx R500) for a contract I NEVER EVER signed up for. Also mysteriously two days before Christmas a WHOPPING R704.50 was deducted from my account!!!! There is NO WAY I could have wracked up that type of bill for data used. Since then my statement has reflected goodness knows how many credits and debits all more confusing than the last. I have spoken, pleaded and begged both our local Telkom store and the Customer Care Line call centre to get some living breathing soul to phone me to rectify this TOTAL and UTTER MESS!!!! To date not a single person has acknowledged ANYTHING!!!! And my contract has not been cancelled. I'm heading for legal action and taking the matter to the national press/ media. This is DISGUSTING!!!!! I have had good service from Brattleigh at the local store (he faxed the written cancellation to head office) but as for the rest - *******!!!
