Bad customer service

I took my vehicle in on the 8th of April 2021 for repairs and I was given a turn around time of 8 working days. I called in on the 7th day to find out the progress of the vehicle. I was informed that the car was at Quality Control. On the 20th being the 8th day I called trying to find out what time would the vehicle be ready for collection. I couldn't get a straight answer from Rossi, she ended up putting the phone down on me. On the 19th when I called in she promised to call me back which she didn't I had to call twice, second time I called I spoke to a gentleman who said the car would be ready for collection the following day. Raised my concerns with my insurer. She lies to my insurance meanwhile it is a conference call, called her out on her lie. Promises to give me feedback asap 20 minutes later she calls advising that QC picked up a problem with the car, I ask her what exactly is the problem she says she does not know.
