Nah, you ain't crazy...just a tad bit daft.....
Chase does not have to nor does any servicer who the investor is, there are ways to determine who they are if you know a title person they can pull an O&E, Owners and Encumbrances report on the property and you can find out who the Deed of Trust was assigned to. In Chase's case, they are very solid and the Note and such is in a very safe place, they do not loose their collateral, I have been on collateral reviews with Chase....they have everything in a very, very safe place....under lock and key with firewalls around the building, can not get a cell call in or out for love nor money....
There is a chance that JP Morgan owns the note/Deed of Trust, they sell between themselves a whole bunch. They also sold out to their own Trusts and CDO's but primarily through the JP Morgan side of the house....
You really need to call, call, call and fax, fax, fax....daily to get some kind of response from them, they are really bogged down and they are trying to get everyone handled, just, yep you got it not fast enough......
So, this is a second job...call, call, call and fax, fax, fax.....the squeaky wheel gets the grease....
