Shoddy/no service/assistance

The most terrible assistance! nobody to talk to and no one who will actually follow up on the complaint that I have. They bill me for service that I do not have, they cannot provide me with Wi-Fi, yet after I logged my move to a new premises and was sent an email with an approximate date that the installation would be done, which was not done, I had to follow up and was told they could not provide me with a line, yet they are still billing me! I have sent emails, chatted to numerous staff on the WhatsApp, no one can actually help and get the issue sorted! I still have not been supp**** with a line/Wi-Fi from web Africa, yet they keep billing me and says I should pay for one month notice????? Notice of what????? Their staff told me they could not provide me with the service, and they would cancel my service...
