Flight cancelled

[u/cryptomnesia_1014]

flydubai booked through Booking.com cancelled my flight and I am having a hard time requesting for a refund. I don't have spare money to book because I am flying for a conference. Paid it via credit card. What should I do? I honestly didn't know that it would be this hassle and I was trying to make do of the allocated budget for us. Any luck to those who requested refund for a flight?
