We have had them treating our pond for a while now, but they have just disappeared and won't return our numerous phone calls - and we've been trying to get ahold of them for over 3 weeks now. The condition of the pond is horrible and it is obvious that they have not treated it in a while (we have been told at least 3 months), but they still keep sending the bills. Their company was Administratively Dissolved by the State of Florida on 9/24/2010 for failure to file an annual report, so they are no longer incorporated. I'm not sure what's going on with them, but I WOULD ABSOLUTELY NOT RECOMMEND THEM! If I could have rated them with no stars, I would have.
