Thermal Techs Heating And Air Conditioning

I contracted Mike to install a gas stove in my kitchen and to connect a BBQ in my yard. When he finished the stove he was to email me a receipt and come back at a later date to connect the BBQ. I never got the email. When he returned to connect the BBQ he forgot to bring the parts so he had to go back to Home Depot. When he returned he have forgotten to pick up the bracket to fasten the valve to the outside wall. He said he would be back within 1 week but never returned. After several phone calls, emails and posts to his website, I have not received a receipt. This make me very suspicious.
