they left us stranded in an airport with no air canada

I highly suggest to avoid egyptair flights. On the way back to montreal from egypt they knew munich was closed due to snowstorm (emails were sent ~3-4 hours before the flight) so what do they decide to do? they board us very very early and quickly start the flight before people check their emails. 1 hour before landing in munich they notify us and tell us they will land in frankfurt (where we can find air canada stantions) ok np. Then halfway through they say we have decided to reroute to dusseldorf (no air canada). they land us there and leave us. They tell us go to egypt air counter they will tell you what to do. When we speak to them what do they say? we are trying but no promises, we are not responsible we are just helping you out, etc... After 8 hours of argueing basically they left us here stranded. They start engaging with us and start calling air canada to book flights from frankfurt to montreal and a train from dusseldorf to frankfurt. A total of 30-40 hours or no sleep and being stranded in an airport with no help. Worst and scariest experience of my life. Do not trust them at all.
