Lawn Care Alert

I called this company to maintain my elderly parents who are in there 80s, as the property was to much for them to handle,There first day was June 28th, came in you could not tell if they have been there, no trimming was done, and they did not cut the boulevard, asked for a refund, they said that they would refund the full amount, still waiting, I've called more then 20 times only to get an answering machine, emailed just as many as I called, its October 28th, and I havent received my refund, I have left messages on voicemail to have the owners info , and no response, its horrible that they would take advantage of elderly people who are on a fix income
