Endless and unresolved Pixelation issues

Ongoing pixelation on all TVs for months. Lost out on the Olympics as it was too painful to endure. A handful of tech visits - all nice and professional - but issue unresolved. Talking to supervisors whom I’ll not name for now. All techs pointing to infrastructure issues in the street. Oh by the way, as a customer I can’t order Comcast to service an infrastructure issue. Has to go through red tape approvals. Working with a new supervisor who seems committed. I am not hopeful but will give it a chance. Customer for 21 years and out of options other than calling AT&T (yes off course I’ve called them already).
