	Pros & Cons from Real Users Pros They told me unless I'm spending $1000 a month they won't provide me a technical call. It took them 2 months to tell me that, then they proceeded to be a sarcastic response to tell me that it's also written on their stupid website. They just fueled a strong competitor. I'll copy everything they did and make it better and cheaper. Bunch of morons can't make enough money....stay away from these greedy bastards! Cons They take about 2 weeks on average to respond to any customer service inquiries.
