Theft and *****.

I need my refund this is ***** and theft !!, I made a booking 1 week prior and never checked my app again on the day of checking in only to find out my booking was cancelled due to an invalid credit card, the same card I used to pay the R810 deposit with and the same card I used to book again since my booking was cancelled. My confirmation no was *** for the 1st of July to 6th
