Glow Green - DO NOT USE!!! I have wasted so much time and energy trying to sort out a problem they caused. At the 11th hour the Engineer dismissed the installation of the boiler (whatever that means!!!!). They gave a slot 8 days later!!!!! Why is there no emergency back up for cases like this - I appreciate it's a busy time of year but surely the company should accommodate for this. The after care is appalling - I have held on the phone all morning - getting nowhere. I have sent emails to customer care and two sales individuals with no answer. How can I be assured the cancellation won't happen again. My tenant has two young children and an elderly mother to wait for 8 days is not acceptable for a large company - the reason I initially went with them is the assurance it would be fitted urgently - that was utter false information!!!! I am still holding on the phone getting no answer whatsoever - do not use this company.
