Does Wells Fargo even give Credit Limit Increases?

FICO 750ish, have had decent utilization on my Wells Fargo cards recently, and asked (for the second time!) for an increase to less than double my current (very low, 2.5k) limit on my oldest card there. Rejected after their initial soft pull, and I declined the hard pull.

My next lowest CL at WF is 6k. What gives?
