Telkom poor service and systems

I recieved a invoice with slapped on interest from a dept collection agency regarding an unpaid telkom account. I havent owned a telkom line in over a year. I canceled my telkom line after i attempted to have it moved to my new residence, however after 4 months and numerous visits to telkom Baywest and taking time off from work for technicians that would be coming out to do my install (with no show). I at then decided that ill rather cancel and move on to alternative ISP's and was sorted out in less than a day. Now i recieved an email and call from dept collectors regarding outstanding account fees and threats yo be black listed? I have a telkom mobile contract on depit with you guys... Surely im not running away unpaid here cant you see this? I then to attempt to settle the matter, which reminded is not my fault, went to Greenacres telkom store... Only to find out they are offline and cant assist me, REALLY!!!??? So the consultant trying to assist me further doing his beat logged a call with telkom on an online portal from a tablet in store, i was told i would be contacted within 10 to 15min...its now been 2 days no show yet again. Can you see the lattern here? I owe telkom nothing... I settled all i needed to at Baywest and was told i didnt owe anything due to no service. So why now am i handed over if this is the case? I have done so much work for telkom in your EC telkom direct stores and this is the thanks i get? Who do i contact who do i speak to TELKOM has no face yet it wanta me to recognize it... Pathetic pathetic. Such potential and its wasted on poor systems and service.
