I was switched to British Gas because previous electricity supplier PFP Energy went bust. Since the date of the switchover on 02/11/21 our economy 7 heating has not come on. Freezing cold house for over a week and no resolution in prospect. Due to a number of medical conditions my partner is considered to be extremely vulnerable. So far have made 4 separate phone calls to BG customer service totalling 4.5 hours. I have been lied to , fobbed off , and cut off. These people are totally incompetent. With the last phone call , i thought i was actually getting somewhere and an engineer visit was arranged for today - he never turned up !!! Their online live chat does'nt work. Their online complaints form does'nt work. There complaints email address is'nt monitored !!! Have tried contacting them through Twitter - so far no reply. How can a company the size of British Gas be SO BAD ? Whatever you do , do not voluntarily sign up with this company.
