2 weeks - Card Transaction

I had an unauthorised charge made against my Discovery Card on the 02nd of August. I called the call centre straight away, reported the charge and cancelled my card. I have had to follow up with Discovery 3 times on when the funds will be returned into my card - and each time I call - I am told something different. I do not see why I a) need to follow up all the time and b) wait 2 weeks to have my money returned to me. I need this resolved as a matter of urgency. I moved to Discovery Bank due to the lack of service from my previous bank, but I do not seem to be off to a good start here :(
