The business provided a repair estimate(09÷06÷11) which I signed(09÷20÷11) and immediately returned to them as they required, as a contract to begin work. They then said they would now order supplies and start the repair in 10 days, weather permitting. The business was to start repair on 10÷10÷11. Weather delayed the planned start until at least the following day. On the following day, the business called just before noon saying they would no longer honor the estimate. They cited other costs they did not realize. Having had the estimate I signed for 22 days, they now said their new estimate would be about four times as much, many times higher than other estimates I have since turned down. I find their business practice as highly unreputable. Consumer beware.
