It has been a while since I have to wait when I call MPC. I called three times - one time with engaged tone, once with 40sec wait, and once 90sec wait. For both times I was connected, the agents had to ask me for my MPC # again.

The wait time was not bad for me. If that was because they tried to even out the wait for other members, I would not mind at all. But if that was because of insufficient staff, that would be terrible - I do not know how long a GR member had to wait.
