TELKOM OVERCHARGES/ uninterested in fixing problem

I signed a 24 month contract with Telkom almost 10 months ago. The contract terms were an uncapped 10meg Fibre line for 499 monthly with the first 3 months free.

I got my first 3 month free and then was charged 650 a month instead of the agreed R499 per month.

I've done about 7 calls to telkom over the course of 3 months and spoken to a number of people in sales and in the billing dept.

Each time I speak to someone in billing the advise they're logging a dispute and that the next month my bill will be adjusted. They tell me to settle the current invoice in full because it will be retified in the next billing cycle.

To date I've settled every bill and paid around R900 in over charges. Ie telkom now owes me R900.

Ideally I'd like to cancel this contract with immediate effect as telkom is in breach of the contract that is both parties entered into.

Id not recommend telkom if they were the last service provider in SA. There after service is putrid and they almost don't seem to care.

If i carry on with paying the 650 instead of 499 each month. I will have paid 3000 in extra charges over my 2 year contract. This is completely unacceptable.
