Frustrated and VERY dissapointed.

After numerous attempts, I am still at square one. I cancelled my membership in June 2021 with a lot of cash available in my savings, which I believe should be refunded to me? But unfortunately you get sent from A - Z with no assistance at all? Even logged a few queries, received reference numbers, but with no success. I managed my membership properly and did not abuse my savings, but now I think I made a mistake. I should not have paid cash for some of my medical expenses, seeing as it is futile trying to get your savings refunded. I am very frustrated and disappointed because I always received excellent service from Fed Health.
