I would suggest to divide your "suspicious transaction" on multiple bank account if possible, if you don't already own some open transferwise or revolut account in addition with traditional account

Your own bank.
Revolut
Monzo
PayPal

One transaction on each and I cycle through them. I do one (1) SE at a time and when I get my refund is when I move on to the next se. That could take one week or one month depending on the company
