Creating topic in forum as seems more likely you get an answer for this kind of thing if you raise it here
For this final gas bill it is more than 6 weeks since I switched before your issuing this bill so you seem to have forgotten to include the £30 automatic compensation you owe me.
My opening read with new supplier is 69034 which matches the estimate you have for 26 Nov. I have no idea where your later figure of 69426 for the same date comes from and don’t care, you can’t charge me for those additional units.
If you think the closing estimate is too low perhaps you should have bothered using the meter readings I gave you to establish the baseline and the Third Party Validation might have given you a different answer. Your system has acknowledged I sent the readings in so the problem of not using them is yours.
I look forward to your next attempt at a final bill because I don’t accept this one. Only two days to go before you owe me £30 for no electricity bill either…
Also approaching a costly (for you) drop dead date before I can go direct to the Ombudsman for my last formal complaint which you have so far ignored…
