How do I file a complaint against a DIRECTV employee

AFAIK you call DTV 1-800-531-5000.

It is against a supervisor I spoke with on the phone. He used abusive language, told me I was wasting his Saturday, yelled at me, and told me this was “his business”. When is asked to speak to his boss he said no, and there was no way to follow a complaint except through the FCC

BBB is often a good way to complain. 

It was my billing, has gone up over 40%. Did not get resolved as they said nothing they can do, no promotions for existing customers. I am receiving less and paying more . Will be cancelling after 20 years because of this experience. He told me I could not file a complaint over the phone. I do have his name and employee ID

In case you haven't noticed providers like DirecTV are bleeding subscribers and $$$. Promotions are a thing of the past. 

I can understand increases due to rises in cost, but they are adding profit to the increases they are seeing, and providing less channels while charging more. When they lost the nexstar channels, my bill should go down because I am no longer receiving those channels, that also means their cost went down because they no longer are paying them for their channels. The fact is cable companies and dish companies are a dying industry due to streaming services. They are trying to get as much money now, before they are virtually non existent. I have decided that I am not going down that road with them. You can now get mushy more for less, they don’t even have NFL Sunday ticket any longer!
