I wouldn’t even give them 1 star !!! We are on a telemetry gauge which was fitted 2-3 months ago so no excuse for no delivery. We are now virtually zero. Have emailed the company, having read about how hopeless the phone is. They have sent a pathetic reply with no indication of a delivery. Said it’s a busy time. Well winter comes the same time every year. That’s your job!! They are in breach of their contract. We had the same thing happen 13 months ago. We were assured it wouldn’t happen again. Well guess what! I encourage anyone affected to contact BBC Watchdog to expose this dreadful company.
