I want my money back

On Friday the 7th of March at 18h00, paid for the items that I purchased at Cherckers Canal. I was informed by the teller that the transaction did not go through. However , when I checked on my banking app the transaction was approved and my account was debited. I informed the teller and she called the frond end controller her name is Patheka. She advised that the transaction is not approved on their end and they cannot allow me to take the items. She also advised that the transaction is hanging between nmy bank and theirs therefore the transaction will be reversed within an hour or so. I gave Patheka my contact details to check with me if the transction was reveresed. She advised that she will not be on duty the next day and she will leave my details for the managers on duty the Saturday to contact me. Till today I haven't recieved any communication from the store and the transaction hasn't been reversed
