I'll agree with this...
I left Dish when I bought an HDTV and they didn't carry SciFi among other channels in HD at the time and they couldn't tell me when they would carry them. So when I dialed their number to cancel I was planning on returning one day. After the asshat that talked to told me that I was lying about why I was leaving I told him to "Fuck off" and I would never, ever, for any reason return to Dish..
I do not, have not, and will not work for AT&T/Comcast/Verizon/Charter or similar sized company.
