Overkill on Request for personal identifiers

Hi, I'm a DirectTV Stream customer.  It works well for us, and we like the price.  Yesterday, I tried to add two additional streaming devices to our current account and was unable to do so unless I entered by DoB and full SSN into the online form, so they could do a credit check.  This is odd.  I already have an account, and both ATT and DirectTV have that information already.  After escalating through 2 different customer services professionals, I got to a manager who still could not accept the alternatives I offered:  1) placing the order by phone, where I'm more comfortable sharing a personal identifier than over the net, 2) going to an ATT store to place the order, or 3) going to Costco, where I originally purchased this service, and placing the order there.  The consistent message is that they required this info for "your own protection and security."  Sorry, rings pretty hollow coming from a company whose customer data has already been hacked, stolen and sold in recent memory.  So, ATT and DirectTV -- if you're reading this, its weird that you even have to do a credit check for a $10/mo add on to an existing account where I'm already paying $100+/mo.  Second, if you lose my business, its only because of this concern over unnecessary collection online of personal identifiers you already have.  I like everything else about the product.
