Just to add to the array of stories about experiences with banks...
Just to start, I had received phone calls from Wells Fargo before about the CoH charge (since I pay for two accounts)... I thought that was all well and good, since they actually called.
But last month, I switched to the 6-month payment on one account in anticipation for issue 11. The day before it was charged, I had made a rather large purchase on a PC I was building for a friend. That charge went through just fine and dandy, so I thought all was well...
On the same day it was charged, I had ordered pizza online from a place I won't mention. Apparently, their system somehow screwed up, which gave them the incorrect mailing address (It wasn't my end, I had the reciept to prove it). So, the bank's system flagged my account as possibly being used in fraudulent activity because I'd made a large payment on parts for a PC, then had a non-US charge occur, and then had the pizza charge which was supposedly to the wrong address. To top it all off, the guy on the phone wouldn't let me fix the problem over the phone because I couldn't remember my "password", for which he never gave me a hint. I had to drive to the bank and wait for over an hour to figure this all out.
It was just last month when this happened. I hadn't realized that occurences were as extensive as this thread seems to indicate.
