Were these signature transactions? While banks might just see this as an inconvenience or customer service issue, I'd dispute every single one of these out of principle on my side. I'd also complain to Visa by reporting a problem with a merchant. It would help if you could figure out the payment processor as well to provide that information. Nothing might come out of it, but I did have a successful case about 7 years ago when the Wing Stop near work required ID for credit card purchases due to the "manager's policy". Of course, I tested this, refused to show ID for a properly signed card, and the merchant wouldn't let me proceed with the transaction by card. I reported this to Visa. I went back within a month, and the signs had been removed. Coincidence? Perhaps, but if so the timing was awfully coincidental.
