The acquiring company, lets say it is Guardian, doesn't really have their name on it... and they could give a damn that the Penn Mutl name is on it...
Spot on.
PM was never a big player. Seems like it was essentially a private label product reinsured by Unum (but could be wrong). Lot's of carriers operated that way.
Could it be that in Guardian's take over of this block of business, the records never made it over? They could be stalling in hopes you have copies that will actually provide them with the information they need?
Very possible. Happens quite a bit when a block is assumed.
More likely the plan has a lot of latitude in defining disability. They are using every bit of the contract to stall the claim.
That's a problem in dealing with a 2nd tier carrier.
