Contract Cancellations

During mid October I went to the Kolonade Retail Park Telkom shop, in order to cancel 2 of my Telkom Mobile contracts. They said they could not help me because the system was down. I went again a couple of days later, and the system was still down. On 27 October I went again. Case No ***5 and ***0 were opened. I called on 12 November and nothing had been done yet. The could not find one of the cases so they logged case ***2. On 20 November I called the call-centre again, and still no feedback. What do I need to do to make you cancel my contract? I know you send automated responses to these complaints as well. Instead, why don't you cancel my contract PLEASE!!!!!
