Double debiting my account

I have been having an issues with my Fedhealth Account, I have been suspended since last year. I called in and spoke to Two agent who were unable to assist me with my account.

I also noticed that Fedhealth has been double and triple debiting me some months. now i am told i owe them money . I finally spoke to the manager Clinton, He has not responded to one of my emails, did not bother to call me and let me know what is happening. I have still not received any feedback from him.
