Went onto my bulb account and find we are £5600 in credit!! No notifications from bulb. Have spent hours trying to sort it out on the phone with bulb, they say I have to submit 3 months of gas meter readings to claim the refund and no I can’t speak to a supervisor!!! I have to wait for a supervisor to call me, I’ve insisted on holding for one but have been on hold for an hour now. They are totally dodgy, steer clear.
