Very poor service from TELKOM. Unhelpful

I got and SMS from Telkom mobile last month saying that my phone was due for an upgrade. We did the upgrade at the TELKOM Clearwater branch on the 10th November. my phone has not worked since. i called the call centre and they could not help. i took the phone to the Telkom Mobile branch in Rosenbank twice. the first time i was told by Richard (on the12th) that the phone will work within 24hrs. NOTHING. i went back on the 13th and was assisted by Jordan. i was promised that they would work on the problem and get a callback. still nothing. no call back. its now a full week and i still do not have service on my phone. TELKOM mobile gives you the worst service ever where nobody knows what is happening and your complaint is obviously not treated with urgency. they are useless and do not understand the frustrations of the customer. they treat you like and idiot and do not fully explain what is going on leaving you to deduce that they themselves dont know what is happening. surely a week is long enough to assist a customer and provide feedback. my patience is wearing thin and i am now highly frustrated and i will not recommend TELKOM to anybody. a service provider with no servie
