Telkom Mobile Bad Customer Service!

I app**** for a contract which was approved. I was told to pay a deposit of R2100 as I do not have a credit history. I was told it would take up to 72 hours and they would get back to me. It has now been a whole WEEK with no response. I went to fourways mall branch and they can't help me. I've tried phoning the greenstone branch and the phone just rings. When asked why, their response is that they're short staffed so they can't answer. *******! Very unhappy and still don't have my device!!! The staff just don't care!
