Hi @DRennie all ways to top up here (scroll down the thread in the link) https://community.o2.co.uk/t5/Pay-Monthly-Pay-and-Go/How-can-I-pay-my-bill/ba-p/1014090
However, the first top up must be done with a shop voucher.
If you are having issues that this doesn't resolve, please contact O2 customer service.
