I have been writing to you for so long. You failed to provide a service to me in one of my properties with a family of asthmatics.your engineer came to fix a leaking valve and promised my tenant to come back and fix the problem. Three weeks later my tenant asked me when will the engineer come to fix the valve. Bhc told me to hire a private contractor because we have told you the problem so it’s not our responsibility. With a great difficulty I managed to get get them to fix the valve. I have paid them £780.30 for three properties and I am looking for a refund . They are not discussing this issue. For one valve on a radiator is expensive at £780.30 I have been with British Gas for 20 years and never let down. Landlords beware.
