15% never paid back

Checkers Sixty60 shopping app. I am still waiting for funds to be reversed into my bank account since 29/01/2021 plus refund for the mince that I did not receive, I would not have noticed if I didn't order again and now the same thing... its 15% onto of my order amount this is a legitimate ****! Even if its R2 or however small the amount is if you do this to all your clients you are *****ing a lot.
