Termination of Contract

I got into a contract with 8ta Telkom that expired in May 2013. Thirty days before expiry I sent a Cancellation form and faxed from an 8ta Shop at Clearwater. Some weeks later an agent called to explain the technical winding down process and told me that last payment would be in May. Two months later my account was debited for R180 and later R330. Needless to say I reversed all. What a huge jump (R180 to R330). In October a consultant helped me lodge a query (Case No ***) but to no avail. Three years later my account is still debited and I reverse them. <br> By the way my previous telephonic complaint with an ICASA staff was emailed but never resolved. Everytime I reverse or fill in stop payment forms costs are incurred, but because I am wronged I pursue it. I hope you will help me resolve and finalise this matter. <br>
