Horrible customer service

Telkoms communication sucks! I app**** for a contract. Had someone call me went through the vetting process. Out of nowhere I get debited. When I request for them to call me back no one called back. I had to request for a callback with regards to one of their contract to get a call back. I guess they only call when a possible sale is involved. I was then told I was pre approved. The wording itself doesn't make sense.. If I'm only pre approved why are you debuting me?? Shouldn't it be approved for the debit to go off. Even so why are you not communicating with me. There is no communication that I have gotten so far except a sms saying I was pre-approved. No word on my device.. Just my money they has gone out! I've basically paid for something I don't even have yet. It's almost a week that this debit order has gone off and in sitting a pre-approved sms.
