higher than usual call volume !?

Been trying to get a hold of someone from their billing department for the past 4 days.

I keep getting the message " We are experiencing higher than usual call volumes , please call again later" the the call ends.

Using their online chat also disconnects before i even get an agent.

I wonder if this is due to their recent lay offs that makes no sense and now they are relying on few workers to pick up the load while we pay premium rates for sub par service.
