Yes, we’ve troubleshooted this before. Sometimes your bank charges you simply for using your card for the transaction. That charge doesn’t actually come from our company and that payment doesn’t come to us either, it goes directly to your bank as a fee.
It’s only happened to a few others over the years and it’s very random when it does. I think it may be a State to State thing - so sorry your bank did that.
Hope you’re doing well and looking forward to seeing your homework and progress through the course!
