Paying for no service received

<p>I received a rooter and simcard from Telkom that I wanted to send back. They could not help me with any details for the collection and we do not have a Telkom office in Bethlehem. So I had to contact the courier company myself and organise collection. When the courier company came to collect, they did not have a return address, so they left without my package and only returned 2 days later. This happened at the end of June 2016. Ever since Telkom has been deductinh huge amounts from my bank account. Even though I do not receive any service from them. I have phoned every month, twice a month since June and they still have not cancelled the contract. Every time I phone they have no idea what is going on and I never receive any return call or followup. Their turn arount time is supposed to be 72hrs, but this has been going on for 5 months now. </p>
