Warning: Unethical Landscaper

I recently hired PRESTIGE LANDSCAPING, based on their advertisement in this newspaper. They were to re-sod my backyard but ran out of sod and promised to return in a couple of days to complete the job. I made the mistake of paying the bill in full and (you guessed it) they have never returned nor have they returned my numerous calls. Checking with the Better Business Bureau I discovered they have had 4 other complaints in the past year. Its been over a month and I have little hope of a resolution but would like to alert the citizens and possibly prevent anyone else from getting "burned."
