I had the same problem as Vince above. I cancelled with them due to their work hours conflicted with mine and I would have to wait a day just to receive one email from them. They then guaranteed a full refund since they never started the project. I have now waited a week and have escalated the problem with Paypal, and now they say they are not going to refund the money.
Please save your money and don't use them, they are a fraud.
I used seo companies before but i was not happy with the results. Then, i found SEOXperts India in google and started with a sample project, they were awesome. Most important thing about them was they always provided me with what they are doing and always kept me in the loop. Now, my site is getting more than 15,000 hits a month. Its amazing. Give them a try if you want good value for your money
