Comenity review: Dell pay credit account 3

Comenity Capital bank recently took over Dell Preferred Credit accounts. The account transfer process is a fiasco.
Comenity sent new account numbers via USPS but, for many of us, the mail never showed up before payments were due and the not yet receive account number is needed to sign up for online access.
To infuriate customers even further Comenity sent email stating:

"Your new account number was sent in the mail in late September. If you haven't received it yet, don't worry! Simply contact us at [protected] (TDD/TTY: [protected]), and we will assist you promptly."

That number is answered by an automated system that delights in telling you that it will not disclose account numbers over the phone. Working the automated system through several prompts to get a live person gets you the same result from the representative - no account number over the phone but we will USPS mail it to you again. How very helpful - not!

This was entirely the wrong way to handle the account transfer. The right way would be to create new Comenity accounts with the ols userid/password. Or use a secure online method to disclose the new account number. One can buy a house online and transfer all legal documents securely - why cannot Comenity pass account numbers online securely?
