Google Multiple unauthorized charges Mountain View California

For one month now I've been going in circles with Google support specialists over 241 unauthorized/fraudulent charges that appeared on my bank statement for $2.49, yet they keep on insisting there are no fraudulent charges and closing the investigation. I'd suck it up if I made the charges, but no one has access to my card information (or at least I thought so until those unauthorized charges) and there is nothing in my Google pay/play purchase history to suggest I made them, yet it is being implied that I somehow managed to stay awake for 40+hours and charge $2.49 for every 15-30 seconds between the 12th and the 18th of July.
