Billing amount not the same as agreed on contract

<p>I took up a WIFI broadband deal with Telkom on a 20 gig day/20 gig night promo, the deal was for R499 inclusive of all costs for a duration of 24 months. Today I'm shocked to learn that Telkom ups my bill to R551 every month because on the statement there's other items that are charged for of which we had not agreed on and it wasn't specified as being part of the bill. I sent an email to Telkom via their website to explaining the anomaly found but no one from Telkom has bothered to make contact with me and if you try to contact their lines, believe me, you'll be even more angry as no response will be provided, if you're lucky to get someone on the other end, you'll probably be redirected to all departments and still get no assistance and reasonable explanation. The Price they are charging me is even more than the 30 day/30 night package.</p> <p> </p> <p>Feedback that I receive keep on changing because I got sent a statement for the month of Aug and it still says I am supposed to pay: R557... No one once to take action in correcting the error and I must keep footing the bill... How fair is that??????</p>
