Selling my car

I made the mistake of using Car and Classic recently to try to sell my car.
After their initial contact it went down hill.
I wasn't assigned a journalist and the description of my car was frankly rubbish.
The car failed to meet the reserve twice and then they refused to relist it.
Then they told me they were trying to sell it outside of auction and kept sending me enquiries from " potential buyers" which always came to nothingapart from one offer that I accepted and was then withdrawn as they allowed the buyer to change their mind !.That broke their own terms and conditions..
Then they did not respond to my emails and never answered the phone.
I put a bad review on Trustpilot which they had removed !!!
How is that right ?
Avoid.
