Charged my pensioner grandma 100 pounds to come out and check her boiler which wasn't working, Turns out it was just the battery that had died in an easily accessible place which was a Double-A battery, The workmen then continued to use my grandma's own battery to replace the dead one and continued to charge my pensioner grandmother 100 pounds for something that she could have easily been instructed to do or check herself. After reporting a complaint she received less than the amount that she had paid for the call out as a pay off and we left the company. Disgusting
