The Revolution, LLC is a first rate Dish Network company. If I understand correctly they are a franchise that sells and installs Dish Network. What stood out to me is because they are a small family owned business they seem to really care! If you live in Grand Rapids Michigan give them a try I was glad I did.

The Revolution is a Dish Network provider with a difference. They are family owned and run. What this means is when you call them you talk to someone who cares!

Bought some product from this place on 11-28-09, product was defective so returned it on 11-30-09, checked my account and the money was not returned, called them and they gave me some bullshit line that it was done on there end and I should give it more time, I gave it time and then called them back, they said that I would see the refund in 5-7 days, well we are going on a month and no refund, They are very rude about returning my money and now when i call they will not return my phone calls. They asked it the money was going to brake me, It is the principal of the matter not rather the money is going to make or brake me. They are stealing money so check your bank accounts, and credit cards when you have return from this place they maybe scaming you like they are me. And the sad thing is it was the manager that did my return and sold me the product, he will not even take my phone calls anymore.. I give them a big fat 0 for rating. Don't buy stuff from this place, Iam not the first to be ripped off they have done this to my friend also. If you want to keep your money go else where.
