Hi @
Traceyann,
I have moved your post to the help and support with it's own thread as this is a more appropriate place. When you topped up you would have got a receipt with a 20 digit vend code, this vend code may need to be entered manually to get the credit on. A guide of how to do that can be found
HERE.If you do need further assistance please don't hesitate to call customer services on 0330 333 7442 as the community is not manned by customer service and is primarily for peer to peer help and support.
