Mistake on Account and now they Blacklisted me

Telkom has network problems in our area and in 2014 late I reported it, they sent out a technician a month later who saw the fault and 8 month later they confirmed with a Network Reference that I can cancel all my contracts with Telkom which I did and then month end came they penalized me, I phoned and went into the direct store as the lady at 180 said I must go and then Telkom realized that the system automatically puts on a device penalty fee and then they reversed it only to double up on it the month after and since then Telkom has messed my account up, I have references galore for them to fix but they can't, Lebo said the top structure of Telkom mobile is in shambles. In the meantime Telkom got some debt company to deduct R1500 a month off my account to makeup for their mistake I reversed it and then they decided to deduct R15000?????? I reversed it and month's later now they have blacklisted me that currently have a very high credit rating. They suspended lines only to unsuspend them month later and I have made no payment as the account is TOTALLY WRONG
