Cancelled account billing & money owed to us

So we app**** for a ADSL line in 2014, Telkom advised us that they will only be able to assist us January 2015 so we decided to cancel the contract which was confirmed, November we got a call from Telkom to say they want to come and install the line for us and we told them AGAIN that we cancelled the contract. Even though it was confirmed that the account was cancelled Telkom decided to start billing us and taking debit orders on an account we cancelled months before they wanted to come and install the line, there is still no ADSL line (not like we want it now after the service we've been getting) and we are still being billed R549.00 for the past 7+ months. We've had numerous telephonic conversations as well as branch visits at Cape Gate as to where we were promised our monies will be paid back to us on February 13th, hahahaha no monies paid back yet and it March 2nd, Telkom is owing us nearly R3,000 + on a service we cancelled and an ADSL line we don't have.<br> <br> Telkom - Tomorrows Future Today - indeed that's why they take debit orders TODAY on cancelled accounts so they can pay their staff in the FUTURE that is not LOVING THEIR WORK and giving us poor service!!!!
