TV of less than 4 months had pixels go bad. Dish tech was scheduled to come out and assess the TV and put in repair/replace needs. Dish tech determined panel and mother board needed to be replaced (on a Friday). By Tuesday, Dish was no longer working with Samsung and the company my ticket was reassigned to does not have technicians in my state (CO). When Samsung informed me of this they said a replacement TV would be sent and I would be contacted within 3-5 business days. 10 days later, I was never contacted. I called Samsung and they said the original request was approved over a week ago. Again, I was not contacted. They have made no effort to expedite this.
