The keys are scammed, you must give me your account information for me to add the card on. I'll continue to add cards on your account until the amount of time you paid for is read (ie. how many cards you bought)
Usually the wait time is never no more than a day, majority of the time it is instant.
Your giving me your account so I know the time has gone on there. Your account is safe with me several contribs + will vouch for me.
