Taking my money ********ly

It has been a near impossible to task to end my contract after the 2 years I signed for, was up. I guess I should have figured, as there are way better products on the market at better prices, than that which Telkom offered. Nowhere can you find a number or email address to contact a PERSON to help you. So I went into the store. A Telkom technician assisted me at Menlyn on Saturday 22 September, I CANCELLED my contract. I received notification via sms and received a reference number (which I will provide upon contact). But still I am being billed by Telkom. Will someone senior please contact me and sort this out and also arrange for a refund to be made back to me for the money you deducted from my account *******ly.
