how long are coins locked for?

So i donated for 10 coins weeks ago using a debit card, but never tried to spend them, earlier this week on monday i sold one of my chars, leaving me with 103 coins, and today i saw a char i wanted to buy for 105 so i bought another 10 coins using the same card as weeks ago, the payment was fine and my acc shows 113 coins now,

My issue is when i try to buy the character i want it says i do not have enough non locked coins to make the purchase.

I am assuming this is the 10 coins i just added leaving me 2 short for the purchase until they become unlocked.

how long does this usually take, again i paid with debit card and coins already show on acc.

thanks

They remain locked out of being used to trade with other players for 72 hours after being credited to your account.
