We had Toronto Ponds and Water Features come to clean our pond and install a new pump as well as fix the skimmer box. That went OK. But when the pump came disconnected to the hose and we called to have them come and make an adjustment, they failed to return repeated calls and emails. The owner, Ross, simply disappeared. After my fifth or sixth call, I did get a call back from Ross but he hung up as soon as I answered and I still haven't heard back. I finally called another company to come and fix the problem and do regular maintenance. It's a little bit of a mystery.
