Contract Cancellation

I took out a 8ta data contract in 2012, for my son studying in Cape Town. In 2014 I cancelled the contract at the Telkom offices in Jeffreys Bay and filled out all the necessary paperwork. Shortly thereafter the Telkom offices in Jeffreys Bay closed.<br> I noticed that my debit order of R199 per month was still going off every month, and e-mailed Telkom to enquire about it. I never received any reply from them and after several emails over the last two years, the problem still has not been resolved, Every month they deduct R199 from my bank account for something I cannot use, because the 8ta data service is not available in Jeffreys Bay.<br> Please help me to get this contract cancelled.
