I'm very sorry to hear this awful news.
If you can send me a quick private message with your name and address, I'll be happy to take care of everything for you.
Thanks for your prompt response!
Would you mind me asking when you lost your home? This'll allow me to close your accounts retrospectively.
I've closed your account for you and you'll receive your final bills soon. Please note that your gas account will be closed using estimated readings based on your historical usage as a meter reading was not taken on this date.
Please let me know if there is anything else that we can do to help out!
