Hi, yesterday I made a deposit to Neteller.

The process is to generate an invoice from Neteller in USDs and that gives you a Bitcoin address with a BTC amount. I've copied the address and amount manually since I can't scan the QR code with my bitcoin core wallet.
Anyways I sent the payment (already has like 20 confirmations) and on my Neteller account it says "Payment declined" but now when I look on the blockchain for that BTC transaction ID I see that it appears as "Spent" but my credit hasn't been charged to my Neteller account.

Is that money lost? Could it return to my wallet?

I've already contacted Neteller support but they take ages to reply single line emails so I'm losing my hopes.

Thanks for the help!
