Update: we raised a complaint with Motability, and spoke to someone about this on Friday, and have spoken to someone just now, and they are able to reject the car as there was a fault with it within the first 30 days, Cupra were trying to say the second dash part had warped because of the warm weather, which the Motability person said was not right, and we said it wasn’t even warm in March when we collected the car. She said that they will now send a formal email to Cupra saying they are rejecting the car, and if for any reason they refuse, it can be escalated.
There you go – well done!
