I need a moderator to help me figure out a way to get a refund. thank you

What kind of refund are you referring to?

I was attempting to log in and somehow accidentally purchased a friend slot for 500 fg which i did not and do not want.

All purchases of site features like this are final and can not be refunded.
Make sure to not have your gold password on auto-fill to avoid these kind of mistakes.
Sorry, but there is nothing that can be done about this I am afraid.

you are afraid that there is nothing that can be done? Pretty much sums up the integrity of the population that runs this site. Zero percent chance anyone is afraid and 100% chance that something CAN be done. But hey, who cares about truth, facts and credibility.
