I was told by the installer they are having issues with the 4k box, but the customer service on the phone said they just don't have them and they will email me when they are available. I moved from PA where I had the box to Florida and would really like the 4k box back as my 86 inch tv will perform much better. How can I go about getting on a list to get a new box shipped to me to replace the existing box. Or do I just have to wait for an email for this. Thank you for your time.
