British Gss Energy estimates are a joke end can't be overridden by their staff with real readings

"iSupply" was once my energy supplier and refused to take my reading or the pictures of the electricity meter in my empty house.  It cost me £1200 before they were ousted from our energy market.
When we moved home it had Pay as you go meters and I could never get hold of Utilita so we moved to British Gas.  I hoped things would be ok . . move back to a credit meter (promised by BG on our transfer) and never need to buy a top up again.  How foolish was I?
I took the meter readings on the Smart Pay as you go electricity meter. 

All well at first as I topped up the smart pay as you go meter online.   After a couple of months I went online to find that my bill was £0.00 but I had, apparently, managed to use more than 6000000kwh !  (Yes that IS millions haha). Queried . . Resolved? Nope. Looking at my supposedly accurate estimated readings I found that they started ok then jumped backwards.  They reset to zero then jumped forward. I complained and sent the real meter reading which was still in line with normal usage.  They sent a bill for in excess of £2000 which was way over what was expected and based on ????? Certainly not our previous usage.  At this point BG decided that they would fit a new smart meter, great I thought.  Engineer arrived and submitted the current reading in front of me (and it was correct and in line with real expectations).  Following week I look at payment history and sure enough the £2000+ bill was cancelled that day . . . and then reinstated.
I complained but no resolution.  Said they would get back to me within 7 days but no.  The bill has changed to £1700+ but why?  The meter readings are still wrong and there is no foundation for the bill.  I have gone back to the start. 495 days and 5544 kWh standing charge plus cost of electricity=£1596.96.  Already paid in £1245.65.
Bill should be (approx) £351.31
If I can do it why can't you British Gas?
