I've had this card for almost six months, coming to end of promo period. I've put through about $50k in purchases per month, on a $20k CL. My usual mode of payment has been through the WF site, pulling from my WF checking account, paying the current outstanding balance, although I have also BP from BB a few times.
I usually got a fraud alert if I spend more than $3k per day, which I tried to avoid. Pretty simple to clear, didn't have to deal with any humans along the way.
