Telkom we know how to dissapiont

In september I app**** for a landline 4mbps uncapped.I waited 21 days for installation.Up on installation they send me the most incompentent technician they had.He f@cked the whole system by installing my line on someones elses port ,not being able to answer any questions.I ended up being on someone elses port and 2mbps.I phoned and tried to correct this another technician came a week later.He f@cked it even more by installing a new landline and not canceling the old one.Both said not to use the landline.At end of septmeber I decided that the service is poor.I tried several ways to contact and cancel and several ways to ask if someone can assist.Emails ,phoning asking and begging.Up until now telkom stil send me a bill I have not made any payment and will not please hand me over to the lawyers,or please cancel this excuse of a service .
