Telkom is a **** that takes advantage of people

Telkom is the worst mobile network ever, I took a contract of R200 per month with them for 24 months, the last six months, December till present day they have been deducting about R1000 and more every month, as if that is not enough, they even go further by deducting money in the middle of the month. I have called them several times, each time they tell me they have resolved the case and before I know it, they have debited my account. Taking over R2000 a month on a sim card that I am not using anymore because of this issue. I am more than disappointed in your services. I am fed up
