Customer Service

I was sold a Telkom contract for a wireless router in January from someone claiming to work for Telkom. Had a lot of trouble because the router did not work, not even Telkom themselves could verify the "contract" for me, obviously it seemed that I have been ****med. I then stopped the debit order because I had no confirmation that I was actually paying Telkom. That was in February. Then in May Telkom suddenly "found" the contract and threatened me with legal action if I do not pay. I have spoken to numerous people at Telkom (shop in my town, telephone, email, facebook) to no avail. I have not used the router or sim cards at all and requested cancellation of the contract, whereby I was informed that I would have to pay R 1 600. This is just the short version of the problem. One of the call centre agents did promise to escalate the issue, but nobody bothers to answer my emails. Customer service ? Latest reference numbers in a whole bunch collected : REF#_*** + REF#_***
