My mother died suddenly last April and I handled probate. Although her account was with Sainsbury energy, it's really British Gas behind the scenes. When it came to completing probate after selling her house, I gave the final electricity and gas readings. I was told that I was due a refund, which didn't surprise me as my mother had the heating on 24 / 7 and for 6 months I just had it ticking over for a couple of hours a day. They issued the refund, I completed the probate accounts, dished out money to beneficiaries and drew a line under it. I then got a bill, which I ignored as I assumed it was an error, followed within days by a threatening letter from BG about retrieving the money. I wrote a complaint letter which also asked why was I given a refund if the estate still owed money? This was sent to appropriate people at Sainsbury and BG. No response. I then complained to BG via their website. You get an automated response saying they will respond in 3 days. No response, so I sent the complaint in every day for 3 weeks. No response. After an extremely stressful year dealing with my Mother's death, handling probate and having to deal with a nasty money grabbing relative, I didn't need this unnecessary stress from BG. Someone from Sainsbury eventually phoned me today. It turns out that BG "forgot" to bill the estate for 2 months, the refund should have only been for a couple of quid and therefore I had to pay the rest. I explained that probate was completed and the bank account closed and surely as it was their fault they'd write it off. No, and the only compensation I'd get - sorry "gesture of goodwill" was £20. I have had confirmation in writing from them that (1) they used estimates to close the account - even though I'd given them the final readings (2) They got the dates wrong and (3) I was given incorrect information, and they still get off scot-free. There is no "punishment" for being incompetent. So I am going to have to pay the bill as the other beneficiaries won't chip in. I am frankly disgusted that due to an error on their part, BG is hounding me for the money, and won't take any responsibility for their incompetence, especially when dealing with a dead customer's account. Shame on you BG. Shame on you.
