telkom bad service

Dear Telkom, please ask your agents to have time for they customers, I have been calling Telkom Cresta Mall for the pass 3 days, asking for help, the 1st day the lady that assisted me with my contract was not available and no1 else could assist. I called day 2 and she was busy and was supposed to call me back, but didn't bother, on day 3 finally got hold of her and she was supposed to give me feedback in 5mins, its already half the day gone, and I have already called 3 times and every time I give my name, her co- workers says she is not available. who were we supposed to call if the agents / workers cant assist customers. its really frustrating... please assist. my agents name is shiela.
