Poor service

<p>My tablet contract expired at the beginning of the year so now mtn is still charging me for the data. I have made 2 attempts to cancel the data contract as i don't need it. On both occasions i got through to a call center consultant who would transfer me to their retentions office. On both occasions the retentions office didn't pick up my call. i was on hold for more then 15min with no one picking up my call. I have been to the mtn shops to ask what do i need to do to have the contract cancelled and no one can help me or tell me what to do. So basically i am being held hostage by mtn in a contract that i don't need or want. I am being forced by mtn to pay for a service i don't want or need and have tried to cancel on more then one occasion. What they are doing to me has to be ******* and mtn can't be allowed to get away with this. I have been a loyal mtn customer for more then 10 years but am disgusted with how i am being treated now. This is not on!</p>
