TELKOM transfer of line service appalling

We've been battling since beginning November 2018 to get a line transferred from previous home to new home. Telkom cannot provide the same service at the new house and billed me almost R7000 penalty. Then I speak to this person then to that one. Then the system is down. Then the System doesn't connect with that of the technician. This morning the latest is that apparently our previous address is still that of 7 years ago on the system. I'm wondering where they've been supplying a service and what I've been billed for the last 7 years then. I have so many reference numbers already its to laugh at if it weren't for me really being so adjetated by now.
