OK, so it's a United ticket involving travel on Discover/Lufthansa.
Aegean has nothing to do with this ticket - they didn't issue the ticket, and they didn't cancel a flight - and they cannot help you (even if you now have a sector or more on Aegean after being rebooked by United). The only entity that can assist you is United, given that it is their ticket.
I'll suggest having this moved to the United forum as this is posted in the wrong place.
