INCREDIBLY HORRIBLE CUSTOMER SERVICE, GOING TO SUE

In the 25 years I have been a DTV customer, I have never experienced such horrible service as I have the past 7 months.  I moved to a new house so DTV said just bring the main receiver and they would install a new dish and 5 mini clients.  All good.  One of the mini clients doesn't work after the first 30 days, and they want to charge me to replace it.  I give them (Edited per community guidelines) and they say they'll take care of it.  The nerve!  Then I notice they are billing me for 6 mini clients.  They insist I have them, but I only have 6 televisions (1 using the main receiver).  They finally relent and say they will fix the billing.  They never do.  Meanwhile, one of the channels I am supposed to receive doesn't play.  I call to complain, they don't fix it (but I still pay foir it).  And then yesterday, one of my mini clients won't play, the TV says I have too many active receivers going and to remove one.  So, I call again.  The first DTV agent is basically useless.  His supervisor comes on (only took 40 minutes!) and tells me that my main receiver can only support 3 mini clients.  I ask her why DTV sold me 5 and never said anything?  She has no answer.  And when I inform her of the overbilling, she offers to upgrade my main receiver.  What about all the money DTV just essentially stole from me?  She won't address it.  I ask to speak with her boss.  Today, her manager calls and asks me to explain my situation, so I do.  She repeats it, only the OPPOSITE of what I say!  She is beyond incompetent.  It is like a bad SNL sketch that runs towards the end of the show.  I am now interviewing class action attorneys to look in to finding others in the same position and filing a suit against DTV.  Please reply here if you believe you may have a claim as well.
