Help - what do i do
A while ago (1 yr at least) i was flying emirates air canada from karachi to toronto. I was downgraded from J to Q all the way from Dubai to Toronto (Emirates till London and then Air Canada). In London they didnt even let me in the lounge (yes they DENIED me entrance in the lounge with a business class ticket). They told me to "write" to them for a refund. Emirates gave the refund, but Air Canada still hasnt, and they keep telling me on the phone, that they can't do anything and that they will have to get back to me.... what should i do?
