I have a three months account that is not resolved

I have a three months account that is not resolved. Whenever I call the switch board answers my calls then transfer them to the consultant of which none of the consultant answers my calls. I have been sending emails from 25 August 2022, until today I have not received any feedback. I sent a follow up email followed by a call and even today I have not received any feedback. Tuesday 11October 2022 I made a call, spoke to Sera who directed my call to Fezile September as the supervisor and since she went for the investigation process until today, no call and or email follow up was sent. Today 14 October 2022, I called and spoke to Linda as an Switch board operator, she tried several times transferring my calls to the supervisor s and general manager. None of them answered my calls.Linda to ask the managers to address my issue however it is disgusting as their TAT does not seem to be professional I am just sick and tired of their poor services and unavailability of consultants. The dealerships must just stop giving them businesses.
