Deliberately deceptive. After a cold call for PAT testing I agreed to have this done and was quoted a price for this work. When I received the invoice it also included a £9 microwave test and £39.99 for socket testing, which I did not ask for nor agree to. The tiny print on their confirmation letter says I have to 'opt out' of these additional services. What is also sneaky and deceptive is that they are relying on you not reading the small print as neither the sales rep or onsite engineer mentioned these extra works. I do feel sorry for the people who work there as they have to be deceptive to earn their living. I have filled in a form with Citizen's Advice in the hope that it will be forwarded to Trading Standards. I complained and received a revised invoice for just the PAT testing but will never use this company again.
