Benefit Wallet Rejected Claims After Locking Me Out Of My Account

Recently they switched to a new "improved" layout for their webportal. When this happened, my account was sort of deleted. They had a record of my name, email, and social as being linked to an account, so I couldn't create a new log-in. However, when I went to use my existing credentials to log in it said there was no record of that account ever existing. They had limited hours of availability to call (I tried email, they replied back that I absolutely had to call them). It took two months before my schedule would allow for me to call within their limited hours of availability. When I finally got in touch with someone, I had to get transferred 5 times before I finally got someone who knew what they were doing. This was especially aggravating considering the transfer was back and forth between two departments.

This person must be the only competent employee within the entire organization. After about a half hour they were able to set up a new account for me, I had to set up a new user ID and the whole bit... 

This means ALL of my health records are now gone.

This also means that many of my claims are "ineligible" for reimbursement because I am in a new year, and half my claims are for last year. I tried logging in today, and my account doesn't exist again. Just randomly disappeared. Again. I spoke with my company about withdrawing from the health flexible savings account option, and they told me the only way is to wait until next year or to have a qualifying life event. This company makes me want to blow my brains out, which I guess would qualify as a life event...
