Last year around 0600 on BN centre I was roaring along in my metro enroute at WLM-LOWEP and was cleared "Brindabella102 cleared FL350"
ummmmmmmmmm - answer was "not in a metro"
VB had a very similar callsign on same frequency
Poor ATC - throw in probably fatigued from end of back of the clock shift and mistakes can happen.
God bless TCAS
