Help credit card details

[quiggs]

Hi my son has bought coins on his samsung phone by mistake. Does any one know how to get credit card details off his phone

If I recall correctly, you have to do it from the goggle settings on a computer. I'll try to get you step by step instructions once I'm near one next (if someone else hasn't gotten to it first).
