Yeah just not for free unless you bought the system from them and are still in warranty.
Have someone who needs a service call, call you. Quote them $75 to come out the same day.
They would rather call Dish, complain and wait a week for them to send out a tech for free.
This is how I deal with Dish customers....
Cust: Hi my dish doesn't work
Me: it's $100 to send someone out, or we could switch you to Directv for free.
Cust: I don't want to switch.
Me: The service call is $100, or you can call Dish and see if they will send someone out for free. Their number is 800-333-Dish.
Cust: I have been a customer for a long time. They will send someone out.
Me: ok, let me know if they don't want to help you out and we can switch you to Directv.
2 Hours later....
Customer: F***K Dish, when can you install Directv.
Me: what happened
Cust: They kept me on hold for an hour and refuse to send someone out.
Me: I'm sorry to hear that

. When would you like to get rid of Dish and get Directv installed.
