A new safety policy has been introduced to minimize the number of credit account scams and the assignment of other people's accounts. From this time, an account can only be linked to a card if it was used with it for the first time. If someone has shared their account with you, you can use it, but you cannot bind it to your card.
If you bought this account, IMMEDIATELY REQUEST FOR MONEY BACK in your seller because this account is already in use by other cards and you can lose access to it any time!
