PLEEEEEEEEASE CAN SOMEONE HELP ME???????

I am TOTALLY at my wits end after spending 9 hours over 2 days in total on the telephone trying to resolve a billing issue with Telkom, and I am NO further. The Billing department refers me to the Sales Department, who sends me BACK to Billing and so it goes on. As the only telecommunication provider in SA, it is UNBELIEVABLE that you cannot email anybody. So there is NO paper trail what so ever of the communication that has taken place. You wait for at least 20 minutes when you have to re-dial a number, as they can also not put you through from one department to another. Can you believe that the sales representative must get PERMISSION from the team leader to give her email address to customers! I have been billed incorrectly for the past 3 months, I did not pay the over charged amount, and they suspended my line. The next challenge is going to be to get my money back! I have also apparently signed up for a 24 month contract, which I know NOTHING about! I need this resolved but truly do not know where to go to next. In Billing I have spoken to: Nandita, Wasima and Vuyo. In Sales I have spoken to: Shaun Pillay, Lunga, Masipiwe, Letoya, Phindile and Nondumiso ............They could not help me. PLEASE CAN SOMEONE HELP ME??????????
