Trading Standards then court.
They may settle out of court to avoid bad publicity.
After settlement the details of the case - factual re problem,their actions,court outcome - may then become public knowledge but keep it to facts and simple comments like
" I won't be going back to them" .
That could avoid counter actions by them.
Word of mouth is also good.
I had issues with a second hand car from a local main dealer who were appalling. We settled eventually but a couple of items not returned, small £ value but a " kick in the teeth".
No court, just refusal to accept faulty goods route and a deal struck.
Word of mouth now used if asked about them.
