Failing contractual agreement.

I have signed a contract stated that my account must be debited on the 1st day of every month. This morning R2500.00 was debited. This is unacceptable, I have renewed my daughters contract and part of the agreement was that she will receives 10 G data free for the first three months. This has not been given to her. When she enquired about that, the Telkom consultant at iStore informed her that he don't know Telkom's product. How ridiculous can this be. A senior manager needs to contact me soonest. I have already posted a complaint earlier this morning on your FB page and have not received a response. I intend to take this further if I do not get a response. I would like to terminate all my contracts with immediate effect. Why must I keep to my contractual agreement if you don't. At the beginning of the month I received a R3200.00 invoice that will be deducted at the beginning of March 2018. Does anyone in your billings department know what they are doing.
