Absolutely dreadful customer "service". Once waited in all day for engineer no show. When I finally got thru next day they said that I had phoned to cancel!! I asked for the recording and asked why would i take a whole day off work and then cancel it! Annual fee rises every year boiler service due last Nov but earliest slot was Feb. Recd conf email that engineer was coming (night before) guess what? Never showed up. Phoned them (15 mins on hold) re-booked me for following week, took ANOTHER day off work - yep! never showed up. Was furious this time told no engineers available and diff dept sends out the conf emails. Finally go service (the engineer was brilliant) then decided to cancel my agreement (u don't need to give notice) did this over phone a week ago& cancelled my DD. They promised me conf letter, called them today - it had not been generated system error. Another person said I wld rec conf email but another said it's letter only! they just can't get their act together and they DO NOT CARE about the customer. Avoid at all costs!
