I had to buy TF2 keys through Paypal, due To my carelessness I made a donation and did not understand why I can not buy, after searching and rereading I noticed that I made only support, not a method of replenishment. Can you return the payment to the PayPal from which it was replenished?

I could refund the payment. Could you give me your paypal email address?

The refund has been issued.
