We cannot rent movies

In February, I had a tech come over and reinstall my dish. Since then, we've been unable to watch rented movies. Oh, you take my money. You're good like that. But, the movies will not play. We called your service center. You said you'd look into it. Yet ... nothing.

Also, what is this $4.99 movie charge. I did not authorize this.

Please resolve this or cancel my account. Up to you.
