Bad service at Telkom Mobile

I have entered into a contract with Telkom where I get 5GB of data for R99.00 per month over 24 months. My 1st instalment was on the 30th November 2017 which went well through a debit order but on the 31st December 2017 the debit order went through for an amount of R448.00 instead of the agreed R99.00. I called Thabiso from Telkom on the same day and enquired about it and he told me that there was an extra R350.00 fee charged for a technician sent to me. I told him that no one told me about that and no technician came to see me. He then said he had escalated the matter so that Telkom can fix it and in the meantime I can go and reverse the debit order which I did. Since then my problems started as Telkom has been trying to debit my account anytime it wanted with any amount wanted. I have already spoken to more than 10 agents from Telkom but the account still hasn't been fixed. This month alone they have already tried twice to debit my account with an amount of R747.00. I went and reversed both the debit orders. What makes me even more angry is the fact that when you ask to speak to the senior people or relevant people you are told that they are not allowed to give information. They can only escalate the issue to them and wait for the response from them which in my case they have never bothered to action. Last week they have blocked my account and I cannot access the data but I have paid for it. Telkom has the worst service and useless agents who are only sitting there with no clue.
