DISSAPOINTED WITH TELKOM SERVICE!

I'm very DISSAPOINTED with the Service that im getting from Telkom. I bought a contract phone mid November and was told that my first instalment will be end of December. I changed banks and went personally to Telkom branch in Bloemfontein to inform them and updated this on their records. I asked one of the consultants how much am i supposed to pay and He told me i have to pay R579 NOT THE R695 that was showing on their invoice, He told me i was incorrectly charged and he rectified the error. I went to pay this amount at PEP store as i was told. Now im getting sms that my contract is suspended???? I went back to Telkom and ask why and what is happening, the guy told me that he doesnt know what is happening and one of their consultant from Pretoria will give me a call. I received a call from one lady from Telkom , she tried explaining and i asked her how much am i supposed to pay, he said R900 and something, i asked her to explain to me why that amount..she told me to hold on , i was holding for more than 45 minutes until she hanged up!!! I'm really not happy with this service, im only two months with them and already experiencing such low servive...No!!!!! THIS IS DISGUSTING!
