Dissatisfied client

My car was towed to Renew-it Bedfordview on the 19th December 2019, the insurer approved the on the 8th of Jan, mind you the only thing broken was my door handle as they broke into it but still even now my car has not been fixed instead they have been making me run from pillar to post, one time i had to take leave from work to just check if my car was there as no one was picking my calls when i called not even the consultant who was assigned to me. They have zero customer service, instead i have been receiving a message from the tracker company that my battery was disconnected for what i have no clue. I would never ever use their services or even recommend anyone to take their car there. I have been unable to travel to clients as i should because i dont have my car, next week it be two months without my car, i literally had to send a threatening email for them to move on my car only then did they start updating me on the status of my car. Up until now i am still carless.
