Donation of $5 a month not accepting my credit card

My credit card is not known for declining, and that doesn’t seem to be the problem here; the freecodecamp website is actually telling me that my number and expiration date are not valid. I’ve double checked multiple times… is anyone else experiencing this same issue?

Both in terms of spam ads on my learning and also just for the sake of actually supporting this nonprofit… I’d like to get this figured out.

Thanks

Try writing at donors@freecodecamp.org or support@freecodecamp.org, it’s not something we can deal with here
