Well, this is what happens when you do not check QSL information! Here is a pile of QSL cards for 9M6XRO, but because the sender did not put "QSL Via M0URX" then of course they have gone to Malaysia Amateur Radio Transmitting Society. the cards are with John, 9M6XRO amd we will now have the expense of re routing the cards to the United Kingdom.
CHECK the QSL info BEFORE you dump a QSL into the bureau.
QRZ.com profile quite clearly states "please do not send your card via Bureau USE OQRS."
Most of the QSL cards should have been requested on OQRS avoiding this problem.
