Just can't get their accounts right!!!!

Once again we have an issue with our account and Vodacom suspending our phones, we have been battling since June with this account and it is still not sorted. Numbers that were supposed to be cancelled in June 2020, still appear on the statement and then we are told to pay it first and then it will be sorted...., I don't think so; it is not our fault their accounts department does not know what they are doing? After my first complaint, we got a phone call from Senzi in the Special Operations department, but to date it is still not sorted, and you can't get through to her on her number? Don't think you can speak to a manager, it is just not the done thing; we have now demanded that the financial manager call us back, whether it will happen remains to be seen, we have had enough of Vodacom and staff that don't have a clue what is going on; you speak to so many people and get shunted from one department to the next.
