This number is legit and the company is credible. They are based out of Meriden, CT. I spoke with many friendly people all with Jamaican accents who were very helpful and polite.
The lines "DirecTV have new satellites up" and "DISH Network's dish is higher in the sky" are just sales pitches to get you interested in buying their service. They sell both DirecTV and DISH. Bottom line is they can install the service and deliver the promised pricing.
About a month ago I signed up for DirecTV service through the official website. It took over 2 weeks for one of their installers to visit my house. When he arrived he seemed very lazy, and I could tell he didn't want to work given the very humid August day here in the northeast. He spent no more than 5 minutes at my house stating there was no way I can have DirecTV service because of two trees that were in the line-of-sight. He claimed he would "send a supervisor for a second opinion". This is something they say to skate away from the work site. No supervisor ever actually comes out.
Immediately the next day, I got a call from this number. I believe the DirecTV installer sold the information from the inside because they knew everything about my current situation. They claimed they could offer me DISH service and would mount the dish so it looked over the trees. I stated if I could receive some sort of satellite service, I would purchase their plan. Not even a couple days later I was hooked up and receiving every promised channel. The installer did an excellent job and was very friendly. He even said he could of got me DirecTV if I wanted it (found a line-of-site), but I already tried that route and DirecTV ended up losing a customer.
Received a call from them, called back and apparently its dish network based in CT, but what makes no sense is that i'm in NY... so its a scam as far as i can see it.
