Still waiting for a number change

I app**** for an unlimited sim contract from Telkom Mobile at the Ballito branch. I was assisted by Mesuli Ntuli, I explained to him that I need the contract to be activated onto an existing Telkom Mobile number. He mentioned that this would not be a problem, however two weeks after the contract was approved the number change still has not been processed. I continuously need to swap sim cards in order to use the new unlimited contract. I saw him this past Friday and he explained that I should have received a response from Telkom regarding the matter as a call was logged. Apparently the turn around time is usually three days, I have been waiting for 9 days now. The service at the Ballito branch is usually excellent, I don't know what has happened this time round. I need this resolved urgently!!!
