My husband had this problem all week and finally got his METV processed yesterday. We called the Thai Embassy in NY and she told us to:

Use a debit card
What actually happened is that we used a debit card and the Thai bank - Kasikorn refused it. The bank contacted my husband’s bank in the US and told them it needs to be authorized by my husband. When he told his bank it was fine to make this payment, he put the payment through on the application and it was processed.
This was a very frustrating experience to say the least. The Thai Embassy’s Visa Officer was fantastic, very nice and very helpful.
I’m. US citizen and applied this week. For proof of current location I downloaded my drivers license and it was accepted.
I want to note that my husband applied at the same time as I did. His payment would not be accepted. He tried multiple times using different computers, different credit cards, etc. After 2days of rejection we contacted the Thai Embassy and the Visa Officer told us to wait 15 minutes and use a bank debit card. It finally went through, but what we found is that the Thai Bank - Kasikorn- rejected the card payment and contacted the bank in the US. The bank in turn contacted my husband and asked if he wanted to authorize this payment. As soon as he said yes, and resubmitted the payment, the application went through. The Thai Embassy said this has been happening alot since the Visa Application was revised.
