So yesterday I tried to buy three games, but a message appeared saying [error could not complete your purchase, please try again later, if this continues happening contact steam support]. At first I thought the card was off or that there was no balance, but no, everything was in order. Then I thought it was the bank, but no, that wasn't the case either. Next, I tried to check if it was my internet connection, but there was no problem. Then I contacted steam support, but they told me that the card I used is not from the region where I live. The thing is, I have used that card thousands of times on steam where I am now, I don't know what is happening.
