I put a star because I am forced otherwise it won't let me publish, because for me it is 0. As far as I'm concerned, you have not been x correct, so a very negative review .. installed the new boiler, it gives me the same problems as the old one and not you want to solve the problem by inventing a thousand excuses, in addition to the fact that on the contract I had included maintenance and a blue sticker that were never carried out. Really unprofessional, I feel cheated!
