Poor customer support

My TV has been flashing from black screen back to TV for about 7 months now. It has literally become unwatchable for a solid hour until it clears up, if it does even. I tried live chat support and talked to Camille B. and Isabelle G. The first chat with Camille timed itself out. Isabelle G. said she was going to schedule for a technician to come out and then straight up left me alone in the chat for 10 minutes and it closed due to inactivity. That is extremely unsatisfactory. The fact that she didn't inform me when or even if a technician was going to be scheduled. I then tried to call support. Went through the 8 extension button presses to get there, only for it to force hang up on me the moment it actually started ringing. I wasted about 2 hours on your customer service and got literally no answer to my issue.
