Telkom staff is disrespectful and underestimate people!!

I opened a phone contract with Telkom, Sicelo Vuyo Ngwenya was the one who was helping me. My monthly invoice is R789.00 including 100 minutes with any network. My second invoice is close to R1600 because Sicelo did not close my spending. I went to the store the same week on Sunday and I asked Sicelo what is happening, he said he did not close my spending but he will close it immediately and he does not mind paying me the money I used because it was his mistake, he promised to pay it when he get paid. He said I do not have to take it up to the managers because he will pay for it. Today I sent him an sms telling him that I will take this issue to his manager because now he is not trustworthy, he said it is okay, I can tell his manager because he sent me an sms asking for my ID number so that he can pay my account the money i used for call. First of all i cannot give a stranger my ID number and secondly i did not see the SMS and he did not even bother to call me, now he said he won't be able to pay that money because he paid something off, so i will have to wait until he has money during the money. I mean why is he making his problems mine!! And who said i do not need that money, in other way he is saying i must sort myself out. Now i have to pay the money that i dont even have, now i have to suffer becauseof him, he also sent me a text saying that I knew about the spending because I received SMS's telling me that my 100 minutes are depleted. DID I ASK FOR UNLIMITED CALLS? DO YOU THINK I WAS GOING TO INCLUDE 100 MINUTES IF I KNEW I CAN MAKE UNLIMITED CALLS?? Sicelo disrespected me and he underestimated me. How can he say I knew about this whereas he is the one who did this for me, I am angry and I don't want anything to do with Telkom anymore!! Their staff is disrespectful
