The worst company I have ever dealt with!! It star...

The worst company I have ever dealt with!! It started when they charged my credit card 325% of the dollar amount I had authorized for January 1st, 2021 payment! I have wasted over 20 hours on 7 phone calls, 2 emails, (unanswered, a complaint to the heakthcare.gov office, and a call to my credit card company. I was able to receive a couple of small refunds, throughout my many calls to customer service reps. All agreed that I had been way overbilled stating that I would be refunded the agreed amount of the overcharge. 6 different reps told me this, but not one followed through!! I will be filing a formal complaint with the AZ Insurance Commission next. I would not recommend this company to anyone, period!! Very unprofessional, no follow through, fraudulent charges, unauthorized to my credit card, with the worst customer service I have ever encountered, from any business!
