Perhaps not help but have you checked out: https://help.bulb.co.uk/hc/en-us/articles/360006306551-What-do-the-prepayment-meter-errors-mean- which says:

card not accepted
The meter is having difficulty reading your card. This could be either a meter or a card fault
Wipe the card with a dry cloth, insert it back into the meter. If this doesn’t fix it, get in touch.
