Complaint Review: Quicken Loans

I currently have my mortgage through Quicken loans.  I have been a customer for tears.  I received a letter in the mail (7/18/2016) stating that my mortgage has been sold to Fifth Third Band.  Remember Fifth Third Bank used to be GMAC General Finance until it went belly up.  Well, it states that my next mortgage is due with this bank on 8/1/2016.  That's 2 weeks from now.  I have no new loan number to tie a payment too.  2 weeks, get real.  VERY disappointed with Quicken.  Used to be a big fan of them.  No longer.
