CAMBRIDGED RIPPED ME OFF

On Friday, I went Cambridge Food to purchase a few things which I was charged R92 couple, I paid with my debit card and the transaction went through. The cashier said the transaction did not go through, I then added airtime and it was R100 and something afterwards. We swiped my debit card and both transactions went through. I get notifications of both transactions from the bank. I went back to the store and I was advised that the money will be reversed. The money is still not reversed into my account. I HAVE PROOF OF ALL THE ABOVE.
