Extremely unhappy client

I sent my car in for assessment for hail damages in March 2024,I got a booking for May the 9th and a set quotation.Upon arrival of booking date 50% deposit was paid,a month later there was an apprent increase of 25k to the original quote.When I complained that I do not have the money because it was not discussed prior they told me they could no longer proceed with the repairs.Collected my vehicle a few days later with no repairs whatsoever.
