screwed by favor

my parents recently gave me a $250 Favor gift card that they sadly didn't realize was for a grocery delivery app. Upon trying to place my first delivery with the card, my account was banned. The only help center I can find asks me to log into my account first, which does not work. I get a log in code sent to my phone, but nothing on the website to prompt me to enter it, so it sits on the log in screen and doesn't let me sign in. I can't find any other way to contact favor for support. That money was really going to help and now I feel fucked and like my loved ones hard earned money is wasted
