Having been promised a call from an engineer I am still waiting! Have phoned BG four times this week, been on hold for up to 30 minutes, call was cut off once and have been told that I will get a return call from the call centre team on three occasions but nothing received. They say that the dropping out of the Alfen charger is a known fault and the only solution is to hard wire it via CAT 6 cables from the router.
