Terrible after service!! I had a new boiler installed only 6 months ago and it s broken down. After reporting the problem to intergas they said they had no technicians available for a week. We accepted the delay and waited for the arranged day. When the arranged day arrived we received a phone call from the technician saying he wasn t coming and wouldn t be able to come out to us for another 6 days because he had a bad back!!!( poor bloke) When my partner contacted the customer services explaining we had been left without hot water or heating for nearly 2 weeks while looking after our young child, my partner has arthritis and myself a builder with a bad back, all they suggested is that we keep BOILING THE KETTLE
