Disgusting service

In Dec I got a cold call about the new Telkom Mobile LTE service, and got bul**** into accepting the service. The next day I decided to cancel (as part of cooling off period) and called in to cancel. This was confirmed and it was agreed no fees would be deducted. In January I got billed the first month, and in February I have had a R4500 termination fee deducted from my bank account - which was never mentioned during the cancellation. After 2 weeks of phone calls, the Call centre cannot help, and can only say they are investigating......after taking my money!
