Thank you for your response, Yankee.

As previously stated, I would like my transaction fee returned along with the BTC that I paid for but was not given.

$498.95 (with ZipZap's fee added) got me just over $450 worth of BTC, leaving me short over $20 in BTC.

This is my ZipZap account number: 304074966

This is the destination wallet for the transfer: 17YUprif2teV1zeYfsHL2sYfYpCa5vvKkM

My refund can be directed towards that wallet.

All told, you owe me ~$40.
