Complaint Review: Comenity Bank Overstock Credit Card

I made a big purchase at Overstock.com last year. Merchandise took almost a month to be delivered but sound too good to be true the fact that I could pay in 12 months with no interest. In my last month of payment I was surprised with $541 extra in my statement. I contacted customer service and I was never treated this bad in my whole life. Attendant and supervisor were both extremely unprofessional, rude and none of them were able to work the issue out. I honestly feel like I was pranked. I contacted them again thru facebook messenger, so they opened a ticked and told me that they would get back to me in 2-3 days, it is been a week and guess what? NOTHING! I have seen thousands of 1 star review regarding this company´s policies, how dishonest they are and how bad their customer service is... but I feel sorry for people that will fall in that kind of trap like I did, and I am posting this review here to let people be aware about what kind of company they are dealing with. After looking over 2,000 bad reviews and people telling how scammed they were, I just cannot believe they are still operating.
