Mercedes-Benz South Africa

Hi I have a smartcarfortwo and had a breakdown on 31.08.2020. I arranged my car to go to Mercedes Benz Umhlanga branch in KZN South Africa. It took them 3 week before I could get a quote. I paid the quote on 22.09.2020 and was told that the part with take 2 weeks to arrive. At that time I requested assistance from Mercedes Benz to support me with a vehicle as I will be waiting for the part. After the 2 weeks I did a follow up of the part and was told that the part is not on the way as the part is on back order and no one can tell me when the part will arrive. I then requested for a vehicle again and a request was send to Mercedes Benz of***e but there is no guarantees that a vehicle will rented for me. So now I have paid for the part and I am without vehicle since 31.08.2020 and to date no one can tell me when the part will be here or if Mercedes Benz will grant me a vehicle. The problem is that I am starting a new job and I am not sure how to go as I am 1 hour away from the factory. This morning 22.10.2020 at 10h45 I received a call and the the latest is that they expecting the part in December but no guarantee on vehicle to help me during the time that I have to wait for my vehicle. The reason for might not getting vehicle support is because my vehicle is aid up. this I understand. But the fact that I have to wait for the part to come in December is unacceptable. The smartcar is a regularly production car and I think the parts should be available. If the the part is not available then its for me to suffer this problem. Also be aware that I have paid already. But the effort that is done to satisfy the customer is very poor and I am very furious about this... I hope there is someone that can take my request serious.
