Incorrect billing

I logged a call to cancel my telkom data (ISP part) last month. The technician insisted to move my line into a pool and instructed me to tell my new ISP to manage the line. After informing the agent that i dont wish to move the line, just cancel the data, she insisted this is the process and continued. Shortly after this I informed Telkom to stop the cancellation and that I wish to remain on Telkom ISP. Telkom assured me that everything is fine. 30 days later my line is suspended and I was informed by Telkom wholesale I needed to inform my new ISP to manage my line. I DID NOT WANT TO MOVE MY LINE OR DATA! I instructed Telkom for the 2nd time to remain on Telkom ISP via [Email Removed] They migrated the line out of the resource pool back onto telkom ISP. Only in ERROR, suddenly my line was syncing at 4Mbps instead of the 2Mpbs I had before the line suspension. Nor was I on the correct uncapped package. I had to phone again to have the line DOWNGRADED AGAIN. Now I have to foot the bill for all this INCOMPETENCE? Suddenly my bill jumps from an ave R630 per month to R1592.13! A service charge of R694.74 added! For what? No-one visited my home nor installed any new line/service. Unac
