Smart meter app is shockingly bad. So slow and out of date. Never says the correct balance. First top up £10 which has been taken from my bank on my bank statements which never arrived on smart meter no email from BG no receipt number from BG. Still trying to contact BG recorder telephone message says sorry calls can take 45 minutes to answer please call back in 48 hours and then cuts you off. We was emergency credit as meter had only just been installed. So we tried agin this time only £5 which took one hour to register on the meter. We thought at last let’s try £50 but apparently BG app said we had reached our limit for the day. So we then had to wait until midnight to try again which at last it worked. I thought great £55 on gas smart meter. App still says we have a total of £3.88 which was updated at 12.00 am on the 9th Jan it is now 23.55 pm on 10th Jan almost 36 hours later and it still says we only have £3.88. If we manage to get through to British Gas I want them to come remove these so called Smart Meters and give me back my old pay as you go card and key meters.
