Eastgate Mall bad service

Saturday 15 December went to telkom Eastgate mall to upgrade, was helped by Gomolemo, the application did not go through as I was advised that the system is hanging , so I told her to cancel the order as I won’t be able to come back to collect the phone she said it’s fine , from Tuesday I can’t use my SIM card as it shows no service , when I call customer service they adviced that the order went through and has been activated but I did not even receive the phone and I’m told that I need to go back to the store to cancel the contract. I’m trying to call telkom Eastgate I’m told that they are not allowed to take calls , I spoke to Analisa who told me that she will pass the message to Gomolemo but a day went by no call , I called back and put on hold for a long time. Then when she came back they said Gomolemo is busy with a customer the store manager will give me a call, meanwhile I can’t receive or make calls ..,. I’m very disappointed
