British Gas
Sent me an (outrageously inflated

) estimated gas meter reading while I was out of the country. I sent them an actual reading as soon as I was able to. The reading was rejected.

BG then switched to a 'new system' and finalised the accounts on the old system using the inflated estimate.

I have had multiple phone calls with the BG call centre. They can see what the problem is but they don't have access to the old system and each time promise to get someone with access to the old system to fix it. EVERY TIME they promise yet it still isn't fixed.

In the forlorn hope that smart meters might prevent future problems I agreed to have smart meters fitted (the meters needed replacing anyway due to their age). First appointment I waited all afternoon but no show. Second appointment he fitted the meters but couldn't get a signal so left me with dumb meters. The only positive was that a BG employee had taken an actual reading (took the whole bloody meter). Left me with the recommendation that I call BG and ask for a 'Mesh + T2' module to get the comms working. FFS

Phoned BG for an appointment to fit a 'Mesh + T2' module. 'I can't do that, we need to wait 28 days for the readings to come through'. But you won't get any readings without comms!!!!!!!!!!! Gave up. Put a reminder in my diary.
A few days later the electricity meter connected to the network. Not sure when exactly as I wasn't given a display

After 28 days I called again. 'Sorry, don't have any appointments available, can you call back in two weeks?'
Two weeks later I called & got an appointment for Monday (yesterday). Different installer turned up. I explained about the lack of signal. 'I've got a signal' he says and proceeds to work through the configuration process.
I now have functioning smart meters for electricity and gas

It has been pissing down with rain for days, wondering if they will carry on working if the rain stops..............
Today I tried to contact BG about the estimated reading (and failed) so I paid for the actual usage & didn't pay the extra £500. I suppose will need to spend another hour on the phone tomorrow

trying to get resolution
