British Gas are COMMITTED to making their customers lives as difficult as possible. Moved into a rented property 3 years ago that was fitted with pay as you go top up meters with British Gas. Landlord will not put proper ones in or switch supplier, so pay as you go with them it is. After a year, British Gas got in touch to say they were moving all prepay customers over to smart meters, with new top cards and codes and everything. They came to the house, took the old meters out, put the smart ones in and gave us some new cards. New cards didn't work. New cards didn't work for WEEKS. The stress involved was horrendous because of course on a prepay meter, when your amount runs out - you're cut off! No gas, no electric, with a 6 year old and a baby in the house! It was awful. Endless engineers coming to the house fitting different meters and different meters and giving new cards and new cards, nothing working. I was locked out of the account held for this address because of course, the previous tenant opened the account for the property. Landlord would not give us any info on the previous tenant so we could get in touch and ask to switch names on the account to mine, he wanted absolutely nothing to do with it. British Gas themselves could see that there was an account held for this address but they also would not give me any details of the name held on the account, or switch it over without the password that the previous tenants had set. Weeks without help or power. Hours and hours and hours sat on the phone to south africa, because surprise surprise - no UK call centre! I lost £80 in failed top up attempts on dud new meters and useless new cards that they promised to reimburse me for and NEVER did. Eventually, they agreed to open a whole new account in my name and start from scratch. Finally, after around 5 weeks, they fitted a meter and cards that actually worked. I was so happy to finally be sorted and finally be free of this problem that I dropped every dispute with them and just got on with my life, topping up free and easily. Two years later and we've just had emails and texts. We're being moved over to a brand spanking new account style, new top up card numbers have been sent and there's a lovely shiny app as well. My heart dropped into my stomach. They've voided my old cards that I fought like a savage to get, so they are now invalid and they've sent new top up card numbers. Guess what.. They don't work. When I say that I CANNOT do this again with them and that I'm in absolute despair over this happening again - I say it from my whole chest with every fibre of my being and every shred of my soul. These changes weren't asked for, aren't wanted, aren't needed and aren't working. I'm absolutely miserable. I despise the company and I'm locked into business with them due to my landlord not giving enough of a stuff to switch suppliers to the address If you have a choice on your provider, unlike myself, I can't suggest enough that you go with literally anybody else.
