I was transferred o er to BG when my supplier went bust in February. I got bills through in March and payed them straight away. Then there was a back and forth period where they would cancel my bill, refund the money, issue a new bill for a slightly different amount, I would pay it, and repeat.
Things settled down and I payed my DD every month, but have had no bill since April. The amount of credit I am building up has stopped increasing, despite DD payments going in (I have screenshots) but still no bill!
I think they are 6 monthly, but that brings me to October and still I have no bill!
If you are with BG and pay 6 monthly, when does your bill come?!
