Unproffesional

My Car was sent to CMH Opel Umhlanga Via I&I cars in September and till today I have not got my car back. both CMH and I&I cars are keeping me in the dark about the progress of my car. both keep telling me they are going to call me back but never call. It been weeks and two curtesy broken down cars and I'm still waiting for the call from both of them. today 28.10.2020 called the dealer and he said he will call me back and call CMH later they both said they will call me back. this has been going on for weeks. non of these people want to tell me the progress of my car and non will ever call me at least tell me the truth.
