Incorrect deal loaded and i am suffering

A sales assistant at your store loaded the incorrect deal in January and i got the bill on the 1 February and went to the store straight away to have this sorted out. The guy then emailed the billing department and then that was it, he left it. The incorrect bill then came off my account on the 16 February, even though i specified the end of the month. I then called the call center and the lady helped me out and she said she would email me the details of our conversation and that my problem will be sorted out, she never emailed me. I then got my bill today... and it still has not been sorted out. I cannot believe this, i have to suffer because of someones incompetence even though i have gone through so many people to try sort out.<br> I am not impressed and regret moving to Telkom Mobile
