High fees, poor customer service.
Even when my employer changed to a better HSA and I wanted the transfer my funds out I hit problems. First I had to liquidate all investments - so I checked the "sell 100%" on each investment.
Two weeks later when my new HSA tried to pull the funds they prevented it because there was $3.27 left in one investment. When I called their customer service agent basically stated this was my fault, so I hung up and called back.
Now I've had weeks where I can't invest my HSA funds due to their terrible software, incompetence, and poor customer service.
To any employer thinking of using Optum, only use them if you really want to upset your employees.
