Blocked card no warning

My card was blocked and i was not notified i used it on uber to purchase a flight and at dinner and everytime it was declined. 3 different payment methods an app online and pop. No call to notify me or sms or email. Initially i thought it was a problem with the app and then online payment system but at dinner i realised the issue was with Virgin. Very disappointed by this service i cant afford to be without a card in this day and age its unacceptable that these things happen without any feedback. There was one seat left on the flight i had to ask someone else to book for me. Ridiculous
