MWEB Mtalk not working. Shocking disregard of paying customer.

We were persuaded to switch to Mweb fiber with the promise that we will not need a Telkom land line telephone anymore, because part of the service we are paying for is MTALK voip. We now have four voip numbers already that stopped working with a status "CustomerCancelled" and any attempt to register another number fails with the error " Provided account ID can not be used". We lodged a query on their portal on the 30 May and the reply was that a consultant would contact us at 13:30 - 14:00 on the 6 June. This did not happen and any further complaint has so far been ignored. We are now without a telephone service and cannot get any assistance from MWEB, although they are getting paid out of our bank account for this service we no longer have. Shocking service and disregard for paying customers.
