Manulife Group Benefits Insurance Reviews

Manulife is the most frustrating company I have ever had to deal with.
I asked before enrollment what are the eligible expenses under our PSA. I was told financial services was included. I called again to ask exactly what financial services were included. I was told X was included.
I submit a claim for X and it was denied. I call back 3 times and resubmitting things until I find out X is not covered but Y is. I submit a claim for Y. It also doesn't go through. I call to ask why.
The service rep tells me only dental services are covered. I said that doesn't make sense. I do some digging and it turns out Financial services was completely taken off. What's going on?
I pointed out it seems Manulife is playing around and changing things. She said they don't do that. Right.
Their services reps are clueless. Their claims department deny everything. There's no consistency. The website has no email contact option. While waiting for their call centre they can suddenly put me on a silent line that never gets picked up.
Stressful and absolutely terrible.

I have called Manulife 3 times today with a simple question, the first time I was told to call my Colleague info center and when I did they just transferred me back to Manulife. The second time the operator told me he was going to make some calls on my behalf, then I was transferred again to the CIC. Very unnerving to deal with. I should know better than trying to get any answers out of them. Very bad customer service.
