Poor communication

So disappointed with their services, My car was brought in on the 30th of August for repairs. I was advised that after they receive all parts which was received on the 14th of September 2023 it will take 10 to 20 business days. although at times i receive communication i had to constantly call in to check up cause of delayed stages to my surprise i will be told of a new issue of which i was not informed about earlier (it now that it went for coding which again consultant was not sure when its even going to Renault) to arrange my schedule, on the 6 oct was told the car is at the assembly stage once again i call in 13 Oct today, guess what am told that they still waiting for some parts but on the 12 Sep i got a text to say they received all parts bare in mind no one said anything about the missing parts so now i need to wait two more weeks before i get the car.
