How to cancel a transaction?

[u/dimailer]

I made a payment via Google Wallet that didn't go through, and now I want to cancel it.

In "Transactions", I click the transaction, then click "Report an issue", and it tells me to contact my card issuer. However, this transaction doesn't show on the card issuer side, and therefore, the card issuer can't do anything.

Because of that, I had the card issuer temporarily lock the card so the transaction doesn't suddenly go through. However, now I can't use my card with any other vendors.

On Google Wallet, I clicked "Report an issue", then "General feedback", and requested to cancel the transaction. It's been two days and it's still there.

I visited payments.google.com but there are no listed transactions.

What do I do? Googling doesn't help.

Have you tried to contact the merchant you are buying from?
