Bad Service- no communication

I have been trying to contact the person handling my claim for over two weeks. Spoke to two other call centre agents and every time I'm promise that my matter is being sent to Ziyaad to contact me. I even discovered my claim had been approved when their authorised panel-beater phoned me to confirm the booking-in of my car for repairs. Yesterday I was given Ziyaad's manager's tel no. After not receiving contact from him yesterday - I phoned the manager's number this morning and it just rings. It seems the phones there are either engaged or just ring. <br> <br> this is really frustrating as I have to take my car in for repairs next week and I still don't have confirmation details regarding the courtesy car. Even though I have an issue with the engine size - I should know by now where I'm supposed to collect the vehicle.
