Webafrica transfer of ownership and breach of privacy

Cancelled my contract with webafrica due to selling my house. When I did so a person contacted me to ask if I would like to transfer my contract to the new owner. The incentive that I wouldn't have to pay for the notice period. There was a bit of admin involved and they eventually transferred the service and what a mess that was.

First they simply just gave access to my account to the new homeowner, who then had access to all my personal information, usage data, bank details, etc. The new homeowner didn't change the banking details to his own, neither did webafrica inform him to do so, and the next payment went off my account. When I phoned the webafrica call center they basically said they couldn't fix it and that I would have to phone the new homeowner to change the banking information and to get my money back.

After multiple emails and calls they basically did nothing to fix the situation. They refused to create a new account for the new homeowner and I still don't have access to my webafrica account nor do I have control over the access that the new homeowner has to my personal information.

When I sent a mail to the complaints department they rep**** with a short message stating that they the incorrect process was followed and they've informed the manager to rectify, and ended by saying that the complaint ticket is closed. I rep**** to request further information and to get access back to my account and I have essentially been stone walled. I've sent a couple of follow up emails and made some calls to try and get through to someone that can help and have received no feedback or response to any of them.
