I have been charged R 25 extra every month.

I have called multiple time to Telkom to understand my billing dispute finally got hold of a sales rep, who said i should not be charged so much and I should tell their account dept. she transfered to accounts dept. after a loooooong wait, the account exec. said I have to check with sales department. but finally managed to convince that they have to correct it. she said in few days they will revert it and update my account, but its more than a month and I have received next month bill as well but nothing happend to my account. got a reference no for that as well. 17272 <br> I am not even able to reach their call center.. shops are allways in big q. now I dont even know how to cancel the service.. am stuck...
