Tesla Powerwall and Landis &Gyr E470 100mm issues

Hi
I raised the problem of the incompatibility readings between the Tesla Powerwall and the Landis & Gry E470 100mm meter with bulb in November 2021 and spoke to an unhelpful chap. (This was the time when bulb were going into special administration.)
I was told there was going to be a firmware update to rectify the issue to the meter, this has not happened as yet, as I am still experiencing being charged more kilowatts per day than I am actually using. I was told I can’t have a new meter, so can somebody advise what is being done to rectify the issue or a refund of the excess power I have been charged and going forward what to do.
Thank you Graham
