I placed a review here yesterday of my experience with British gas being executor for my mother in law estate, so this is part two. I phoned today to ask why they have given me a new customer number. They should have just changed the name on the previous account which is what I thought they were doing, which they said I had to do to sort out the readings, This should be all the same account, I have not moved in, the house is still empty, I do not own the house, I AM JUST THE EXECUTOR. Having explained this to the lady on the phone, I asked what happened to the 300 and odd units that they have overestimated on both the gas and electricity, which I have paid on behalf of her estate?  Also, why does it not start on 26/03/21 when my name went on the bill, but on the 09/12/20 if this is a new account. The app is next to useless for information as they have wiped their estimated reading off, that was on there at first for the gas and already I have had two different payments owing when I only changed it on the 26/03/21, ( 4 days ago) and why are the bills on there estimated? I put readings on the app like I was requested. My mother in laws customer ref was 8500 5994 0102, apparently this has been closed, do you just keep that over payment then back date the new customer? As she stated she couldn't help me, she stated she was transferring me to Home Move? Didn't  get the chance to ask why she just cut me off, I waited 15 minutes on hold there, then phoned them myself, 40 minutes waiting it said, so I rang their complaints  department to be told their premises had been evacuated, and to call back later!!!  Which I must say made me laugh.
