Poor Service from Vodacom Fibre Department

The level of service I received from the fibre department is shocking . I have logged numerous SR's to try and get relocation , suspension and cancellation and to date no one can give me any concrete feedback . All I get from the consultants is that they will get someone to contact me and that never happens . I have now been billed for WIFI that was supposed to be suspended . I have been calling to get feedback but no one is providing me with that feedback .I have tried to escalate this matter to one of their managers but still nothing happens .
