Hisense a LowSense for service and products

The worst service ever!! I logged in a service request online, called in and then I was told to send an email to their service department. I did all this and all I got was a useless reference number and nothing else going forward to ensure that my supposed "smart" TV would be fixed since it randomly switches off every 5 - 30 minutes even after multiple factory settings resets. I called in twice to follow up and after holding the line for over 40 minutes on the two occasions my call gets picked up and then redirected to service rating. How do I rate a service I never even received and still constantly trying to get with no luck? A smart TV that acts up after just 3 months? I am disappointed in your products and if I could have it my way I would rather have my money back and you keep your service and your overly mentioned "sorry for the inconvenience" in your emails and call recordings.
