Terrible service over charging on my bill

<p>I have a data contract with telkom and I've been chargered for services that I didn't sign up for and I have requested for those services to be cancel, instead no the come back over charging me. I have call for more that 10 time for the past couple of months. My contract is R99 but my bill came back as R643.64 in December I reversed the amount and called about this and the agents tell me about the spend limit that I have be complaining about. In Jan I was debited R303.75 + R99 I left those ones in Feb my bill came as R647.57 I reversed the amount and called again and I get the same story from the agent that the case will be logged. March I was debited 1198.00 same story again case will be logged. These are all the ref they have logged for me. Ref ********** 5, ********** 4, ********** 1, ********** 1, ********** 1. while this issue was solve last year August see ref ********** 8. I am so disspointed in Telkom this is the worst service ever. And now this is affecting my credit record because I have to always reverse the same debit order.</p>
