Poor client service and unable to deliver

It's been over a month they had my car and the only email I keep on receiving from them is "awaiting parts". Had an accident on 26 of May and my insurance approved the claim on 29 May. 16 May I received an email from them informing me that they ordered the parts(unitransmotors) and the attachment showed the letter was dated 3May 2022. It also states that the parts are on backorder from France which can take 14 to 21 days to be delivered. I got anxious and told them to stop sending emails because it's the same update everyday and here I am 28 days later no car, nothing. It's been over a month. Nothing is been done.
