Got Ripped off bad installation plus Fraud as I paid for goods not delivered

We in the end called the guy the tech bungler, yes its that bad. The owner is Michael Carter. We paid him to install ROTEX underfloor heating and cooling system, plus panels and fan units. There was endless delays, the system leaked and could not keep pressure and it was clear it was bad installation. We got another installer in who laughed and says he always fixes this guys mess. Be careful of the usual trick of showing you photos on the phone as these are not his work. Also anyone who wants to sell you a underfloor cooling system make sure they tell you how the condensation will be handled or you will have a mess in your house. I also paid him to import panels from France, I eventually had to pay the supplier and the duties as he had used my money and could not import, thats fraud. Again delays. worst experience in building my new house.
