Debit card declined for purchases in Turkey

[Ken-chicKen]

Hi, I have a problem with buying games on Steam using my debit card. I have a steam debit card issued by a Turkish bank, and I live in Turkey and use Turkcell internet. I don’t use any VPN service. However, whenever I try to make a purchase, I get this error message: “Your purchase has not been completed. Your credit card information has been declined by your credit card company.” I contacted my bank and they said there is no problem with my card or transactions. I can use it for other payments like Spotify. I also tried another debit card and got the same error. I contacted Steam support but they didn’t help me either. This is very frustrating because I have to buy steam gift cards in dollars instead of using my debit card in Turkish lira. Does anyone know how to fix this issue or what is causing it? Thank you for your help.

And what did support tell you?

Hi there,

I looked at this purchase and your bank actually declined it. In most cases this means that there wasn't enough funds on the account for the bank to send us, or they have a restriction on your account, such as that Steam is not set as a trusted online merchant. You should check with your bank what the case may be here.

In cases like these banks often place a temporary hold on the funds until they update the account information and verify that the purchase failed. Releasing those funds back to you may take up to 30 days, depending on the bank and their processes.

Steam Support can only confirm that the transaction failed — we can’t speed up the bank’s processes.

If the charge hasn't disappeared from your bank account after 30 days, get in touch with your bank and ask them to release the funds.

You're welcome to show them our conversation to verify that Steam did not charge you for this purchase.

Thanks for using Steam,

Well Valve isn't lying to you. Or randomly declining your card.

So you have to ask yourself, does the first tier bank customer service person or bank teller really have visibility into all aspects of the bank and transaction configuration and processes? Or are they making slightly more than minimum wage and dealing with very simple problems most of the time, and your issue might be the rare exception that's being their pay grade?

You might have to keep pressing the bank, and escalate your support needs if the problem keeps occurring. It also wouldn't hurt to go back to Valve support and tell them the first tier bank customer support says they don't see anything like what Valve is describing, so maybe a second look on their end is warranted, just to cover the bases.
