Poor workmanship and no communication

My vehicle went in for repairs in December 2022. It took over a week for them to fix with no communication- only when I followed up did I get any update. Upon collecting I realised that there was still a chip in the bonnet which had just been sprayed over, and now there was also bubbling of the paint where they had sprayed. They replaced my bumper, but did not spray one of the small covers, so it looks faded in comparison. I was told they would be in contact the following week to collect my vehicle and sort out the problems - I heard nothing. I phoned and left messages, I sent emails and my insurance broker phoned- but still no response. I finally got a response on 3 January stating they were waiting for a loan vehicle to become available. 20 days later, and I am still waiting.
