Very disappointing experience. Had to make 5 calls to find out where the engineer was, told different things each time. Eventually arrived after 6pm (booked 1-4) couldn't do anything without further payment up front already charged £108 to book appointment. How you expect customers to pay an open ended amount when you can't give an estimate of cost is unbelievable and possibly illegal. Asked them to leave our property - will use a professional company who will estimate and invoice us. Don't expect to see this on your reviews, but if you are the reliable above board firm you claim then perhaps you will print it so customers have an informed choice.
