I want my REFUND, CAPITEC!!

I orded food via Mr D and 3 amounts went off my account but the order didn't show on the Mr D app and was not successful. The amount on my Capitec app shows "pending" it's been like this for more than 7 working days, the other 2 transactions were refunded. When I go to the bank they are not helping at the same time Mr D says this should be sorted with my bank.

The last transaction is still pending which means it's still with the Capitec, but they refuse to give me back my money. Capitec I need money back. I have visited your branches 2 times and no one is helping me.
