Product below standard

Direct TV's receivers are below standard and then they charge you Shipping and Handling to send you a new one and to top it off they added 6 months to my contract. When the 2nd receiver broke down the customer service rep told me that she wouldn't charge me and when I got my bill there it was. I called their customer service department and they told me that there were no notes and she wouldn't do anything about it. You can't trust anything that they tell you and you have no idea there are any notes and they elected to ignore it.
