They did not show up for an appointment I booked to replace my gas meter. Calling their number resulted in one lady who insisted she could not hear me and so simply hung up, then a man whose connection was so bad his voice sounded like a fax machine. Neither could give me an answer to why I booked an appointment, had nobody show up, and had no warning that nobody would be coming and no follow-up on the fact that my appointment was just ignored. Are these people actually legitimate?
