I started to get the NU2001 error two weeks ago. After a total time spent of 3 hours 2 minutes on the phone, over 2 hours of it on hold over a four day period, followed by three separate escalations, nada accomplished.
I called the recommended number. The person in billing couldn't take care of this particular issue, he escalated to another phone queue, queue closed, call next day, start from scratch on the pyramid process and three hours later the top dog tells me they cannot release anything until I email them id, either driver license or passport.
This is after I've already answered all my security questions, proof of account ownership, proof of working credit card(s) etc.
Jumped through all the hoops, still unable to purchase, locked by the NU2001 error.
Indeed, I have jumped through the hoops as well. How any business can say they want your money, and do nothing to enable a transaction to go through is beyond me.
Terrible customer service.
