Worst customer service of any financial company I’ve ever encountered

I had stock in my company, which sold almost two years ago. Our stock was held by Milliman, but they are waiting on IRS approval before disbursing it.

It has taken almost a year longer than we were initially told. When I ask if they have been in contact with the IRS about the delay, they refuse to answer and hang up the chat. This is after they quit answering phone calls from our plan participants, leaving a pre-recorded message that effectively says they know nothing and can do nothing. And for a while if you tried to use the chat feature it would just redirect to the phone number where no one answers.

Why would any company refuse to take phone calls from their clients?!? There is no excuse for such poor customer service.

Not being able to talk to a customer service representative

Been calling for 3 days & I haven't been able to talk to a customer service representative yet. When calling, it says press 0 to talk to a customer service rep, but you never get to talk to anyone.

Also, there's no other number you can call to get the help you need. If I could rate the service, I would rate it extremely poor or give it a 0...
