Bad Service Telkom at the Grovemall

I renewed my contract 2 months back. The phone overheats every now and then. I went to the The Grovemall to report it and to get clarity regarding my new contract. The lady named maphefo was rude. Her cellphone rang while she was "helping me" it was my love phoning her. She answered her while she was 'helping me'. I had to wait for her to finish talking to her love. 2nd thing I asked her about my contract as it was done on line. She took a brochure and gave it to me and said this is how your contract is structured. So now I am asking myself why is the lady there if she can't explain to customers? I had to wait for her to finish talking on her cellphone now there is a questions she gives me a brochure to go through it wow. Then I asked her about the charger I received. She told me to Google the Charger. She said go to Google and Google it. All this time she didn't have a name badge on. I then asked her for her name. She said in sotho 'a ke nyaki'. I went to her colleagues to get her name. She said in sotho ' o sa mofa lebitso laka if she wants my name she must come and get it from me' she was screaming that time. Her colleagues was shocked and scared to give me her name. Then one customer said ask for the manager , I did, the manager came while I was still complaining to the she came loud again she said 'this lady doesn't know what she wants' in front of her manager. I said to her manager this is what I am talking about. Her manager said Maphefo please wear your name badge and apologize to client. She said to me a client 'sesi sorry' with a rude loud tone. Her Manager didn't say anything I asked her 'the manager' if she thinks her apology is sincere she said she will deal with her? If maphefo's behavior is like that when the manager and other clients are there then how will she deal with her? The Manager also didn't apologize I left. My query is not resolved I am not satisfied and I am paying monthly
