Telkom account contract dispute

I logged a dispute ref. number ***7. I received an sms today to say it was resolved. I also received my account today and this dispute was not attended to at all. I was charged for normal Telkom internet lines which I did not use or have access to as I changed to fibre. I was charged for the old line and for the new line. Also the details of the contract amount I signed for is incorrect. I am charged the higher rate and this is not what I signed for. After 2 months of sitting on the phone trying to resolves this, nothing is done. I also emailed the accounts department. I do not understand this.....??? Today I instructed them to cancel my contract as I cannot pay over R2000 for services I did not sign for.
