Telkom taking money on wrong dates and never deducted it from your account

Im so fed up with telkom..im trying to get hold of them since last week... We paid our account that was R2768.. They connected the wifi...witch means that they saw the payment... But then i ask for my invoice..and my invoice stands @R3863.20??? So how does things work @telkom..jou just rob customers because you have their banking details... And then this debit order that you put through on the 13th of each month..whats that all about???? Please go look at all the mails i send you.... I like to cancel everthing with you ********* currupt company and go to another service ..thank you... And need i say this contract works out to be a R1000 a mont..or thats what they tell you to get the sale.. But then the shock.. Telkom you are committing *****... I want nothing to do with Telkom ever again... People stay away from telkom.. There are better service providers out there...Telkom is like the ANC...CURRUPT AND *****..... SIES
