Complaint of sixty 60 App. No groceries and money out of bank account

The checkers sixty 60 was recently changed for the worst. I ordered two deliveries early this morning, the payments were deducted from my bank account immediately on checkout. Two hours later, when my groceries were not delivered, I saw on their website that they're experiencing problems, but no money was refunded. I enquired at the Checkers Preller square branch, but they could not resolved the issue. I phoned the customer care line operator not available. If Checkers knew there was a problem with the App they should have blocked the App. The money is out of my bank account, but on this new App there is no way of finding the "wallet". Checkers sixty 60 I would like to know when I can expect my full refund as the silence of sixty 60 is deafening. Mrs C. Naudé
