The bottom in is money.
First off, If you put a lien against a "company" most likely you won't get your money.
Because all the eq that they have is lease or they are still paying on it. They don't own it.
Second it, if you do want to do anything go stright to DirectTV. Contact Retailer Sercices,Send over copies of your invoices etc....
I have been there done that with PrimeTV and some other companies.....
I got paid for all the work I did,DirecTV wants to uphold up there name, Which they do.
