Health Saver Funds Missing!

I was an incredibly loyal Momentum client for very many years, until their monthly premiums were no longer justifiable for the product offering. By the time I cancelled my contract at the end of December 2025 I had accumulated a substantial amount in my Health Saver account. On beginning the cancellation process, I was guaranteed that my Health Saver funds would be paid out within 4 months of the cancelation. Now, 4 months later, I am trying to find out what is required in order to process the payment, and when I might receive it, but I have received absolutely pathetic customer service. I began the process at the end of March and am still waiting for one of their "superheroes" to get back to me. Disgusting!!
