Topped up wrong card

Hi
I have topped up the wrong card for my gas. I topped up my old one instead of my bulb one. Can anything be done or have I lost 20 quid?

I’m just a customer with no experience of prepayment. However this article https://help.bulb.co.uk/hc/en-us/articles/360006060252-What-should-I-do-If-I-ve-lost-my-electricity-key-or-gas-card- seems to suggest you can use both the old and new card to top up your meter.

However it is best if you contact the Buklb help desk as they are best placed to give a definitive answer to your query.
