theDIBB - Odd Revolt/millers experience

Just been to eat at Millers Ale House and paid via Revolt card.git back to villa and got a text to tell
me how much I’ve spent today. It was far higher than I suspected so a quick check shows the transaction twice (at the same time) but no tip has been taken. Call up and after telling the same story 4 times to a different person each time we get told that it won’t have gone through twice and we should get the money back in 3-5 days. Sounds dodgy as hell
To me but it was left as we check our Revolt card again tomorrow and then call him back.

Anyone else had a similar experience with either a restaurant or their Revolt card?
