"I was having a problem with my dishwasher draining. I appreciated that they were honest. They came out and said they wouldn't be able to do the job for us. It's not a clogged drain issue, but something to do with the pump. Unclogging the drain wouldn't do the trick. I was happy that he offered a refund for the deal rather than taking the money and not doing the job."
