PATHETIC, UNRELIABLE AND POOR CUSTOMER SUPPORT!!!!

I have been a Telkom subscriber for a few years now with my 4MBs line and telephone, I requested Telkom to upgrade the service from the 4mbs line to fibre, since March 2019 when Vumatel installed fibre in the area, i called the Telkom team to upgrade my line to fibre and cancel the 4mbs line, the fibre would be running on the installed Vumatel infrastructure, of which they agreed, an sent out an installer to complee the installation in to my house. I took up an offering for the 20mbs Download and 2mbs upload at R806pm, came with a complimentary router and free installation on a 24month terms.

Since April 2019 the service has been nothing but a painful process month on month, every single month since April, i have been getting an incorrect bill including the 4mbs line and telephone that i requested cancellation on when upgrading to the new service, this has been such a painful process, having to explain myself to different people, month after month. Why does the system not pickup that the service was upgraded, every single agent i spoken too has given me the assurance that this will not be the case the following month, only to have the same thing happen again and again, i have got to a point now were i don't now what do, the billing department which is the recommended team to speak to, has not been able to have this resolved permanently. The service has now been suspended and not able to use the internet at home. This has been thee most frustrating process ever, when your invoice comes in and you been billed incorrectly, how do i now get my service back up and running and not be affected due to an internal process at Telkom, i have no control over? My account has been paid via debit order since inception, i have come to learn today that i don't not have an active debit order listed on the account ....what does one do in this situation? has any one else gone through this, and what has been your resolution. Am i with in my right to cancel the service and seek an alternative ISP, this early in 24 month agreement? Canceling my debit order and paying via EFT will still present me with the same problem, as the amount paid verses the invoice generated will not match,due to the additional services i am paying for, and not enjoying the benefits off. PLEASE PLEASE SOMEONE ASSIST ME!!
