Wheres either my money or my item?!

Hi I just bought an item from a user and it already went thru on my account and it was all set up for me to receive my item but when it came time for the user to send me the item he instead canceled the transaction and it said the money was gonna be put back on my card but it’s not on my card and it’s not in my wallet thru the app. Please help!!!

To get back your money to your bank account allow 3-5 days.
