Flightnetwork is a ****

17 June 2021 I booked a flight with British Airways to East London for the 7/72021 flight was confirmed, the flight was scheduled from 11:45 to 13:20 on the 4th of July the email was sent reminding me of my bookings and the weather and to check in today the 7 July I'm at the airport only to be told that British Airways flights were all canceled. Why didn't they notify me I spent my money to uber and I'm supposed go be at home today standing here stranded and don't know what to do
