Dispute/fault cancelled for no reason

Telkom **********ly charged me for a dispatch that never happened. No technician ever came to attend to the fault. I subsequently cancelled my line due to Telkom's ********* behaviour. I logged a dispute when I saw the dispatch charge of R227.25 on my account when no one had come to attend to the fault. Dispute reference ***9 lodged 25/06/2015. I was to be contacted in 3 to 7 days. There was no attempt to contact me. My next account still showed the charge (with interest now being charged). I followed up and was transferred from department to department (billing - technical - billing - assurance - billing) only then to find out that the dispute was rejected on 29/06 with no reason being logged on their system and of course no feedback to me either. The fault was now to be escalated via an email (but the address would not be given to me) and I was to be contacted as soon as the person received the email. The phone call lasted 1h10min between all the departments. No contact from them yet! Is there anyone at Telkom who actually works at RESOLVING faults not just cancelling them after the outsourced contact centre logs them?
