Impragas has the WORST customer service I have ever encountered in my 67 years. My boiler was fitted on 31.10.19 and was not working properly from the start. Numerous complaints by phone and email over a two month period obtained no result. They either ignored my communications or fobbed me off with promises that an engineer would get back to me and make arrangements to come to the house. No call or visit ever followed. I endured 3 months of a very cold Scottish winter with a sub standard system. Eventually on 4 February a Bosch (not Impragas) engineer attended and immediately found the problem. THE BOILER HAD BEEN WIRED INCORRECTLY! It was never going to work properly! The Bosch engineer was fantastic and fixed the problems in under 30 minutes. I have since requested compensation from Impragas, a request which they have conveniently ignored for the past 13 days. A registered letter sent to their Petersborough address on 31 Jan has been returned to me today 26 Feb as they failed to collect it from the Post Office. The customer service manager a Mr TS is useless and I have been unable to speak to anyone higher. What sort of a business are they running? Lesley, Glasgow
