Lack of customer care

My car went in for repairs at Land Rover West rand on the 24th of March 2021. The wires were damaged by rats. Land rover west rand also refused to give me a courtesy car.

My car was supposed to have been fixed a while ago, they later came back saying that they have to order the parts from the UK. I was expecting them to arrive today and they have sent an email saying that they are further delays with the parts and my car parts will only be ready next week.

All this while I have had to rent out a vehicle at my expense because of delays from their side. They have refused me a vehicle and after phoning the dealer principal he was incredibly rude to me and hung up on me after asking me what I expect him to do?

Please can you assist, this is really eating into my budget, especially when they cannot give me exact dates. What are my rights as a consumer?

I now essentially will be paying for a car I dont have with me, plus a rental car this month.
