Call Centre agent with bad attitude

I called the Telkom helpline asking for assistance with my credit balance then the lady by the name of Karabo assisted me. Firstly She asks me which USSD NO did I use? I reply , then she asks why didn't I check my balances online?? Rather than calling?? Now why would I do that when I've just called the service line?? Isn't she suppose to tell me why I'm not receiving smses to begin with?? Then she asks for my ID, Name n Surname and my physical address "***"??? Then she places me on hold for a while all this just to check my balances????? After the call she doesn't even ask if I want to rate the call because I wasn't happy with her service at all... Dear Telkom as a valued customer you guys are failing me from the constant network problems and delayed smses, to the bad customer service from your agents I'm not happy
