Our oil boiler broke on the 28th December 2020, an order for a new boiler was placed with Glow Green 15th January, an installation date of 29th January was booked in. The installation was cancelled on the 28th January after being advised that a boiler was not available from the manufacturer. - I accept that this is not in the company's control but do wonder why it took 15 days (and the day before the due installation date) to establish and communicate this information when Worcester Bosch were telling people there was a supply issue from early January. The installation date was rearranged for 5 1/2 weeks time (March 8th) despite Worcester Bosch saying they would clear the backlog in 4 weeks. The date then got rearranged to March 5th when a new appointment was found. On March 5th the boiler was delivered, just after 8am, at 8:50am I was informed that the installation engineer had called in sick and would not be installing on that day. Once again I accept that staff sickness is not something that can be foreseen, but would have hoped that a national company would have sufficient cover that should an engineer be sick their schedule could be taken over by others, if not on the day shortly afterwards. I was told that someone would be in contact later that day to let me know when a re-arranged appointment would be made. I received no phone call either on Friday, over the weekend or on Monday morning. I spent 40 minutes trying to get through on Monday morning with no answer, I emailed two contacts with no reply and finally opened a ticket on the website webdesk. Out of desperation I contacted the engineer directly, who stated 'I don't know if it's being done this week or not as I'm away all week on other works', I asked him to get in contact with Glow Green and his response was 'I'll see what I can do, as you are aware there[sic] not the easiest to contact' On March 5th a gas certified engineer was seconded from Crawley to move the 238kg boiler from an unsecure, open to the elements area to an indoor space. The engineers said he had not been advised it was an oil boiler and had no equipment to maneuver a quarter of a tonne oil boiler. The boiler remains in the same place that it was delivered with some plastic bags sellotaped to the outside as protection from the elements. At 2:30pm today (Monday 8th) my wife finally got through to a representative of Glow Green. The advice we received was that the next available installation would be 19th March. Will be happy to adjust the review as the installation ensues
