Cosmic Structures / Cosmic Group Complaints & Reviews

I was interested in investing in Commercial Retail or Office Space at Business Centre in Greater Noida or Noida. Got interested in Cosmic Corporate Park, Greater Noida by Cosmic Group with another project by them Cosmic Corporate Park 2 Noida which sounds appealing to me.
But the Complaints and Reviews for Cosmic Structures creating confusion to me, what is the relation of ARN Infrastructure vs Cosmic Structures.
Even on the website they are showing up with the project in development process with construction ongoing, but reviews give altogether different picture. Just posting pictures with crude basic construction alone doesnt ensure timely delivery of project where already the project seems to be formerly with ARN Infrastructure.
Is the Project by Cosmic at Greater Noida (Cosmic Corporate Park) same project which was formerly sold by ARN Infrastructures as "Globus Business Park" as both were on same Plot No. 10 as commented by some people.
Does investing with Cosmic ensures safe investment ? Because already after ARN Infrastructure's Globus Business Park its now represented as "Cosmic Corporate Park" but still the construction is on elementary phase or its just to come up with some photographs to show that something is going on.

Kindly provide suggestions and reviews because lot of other options in Greater Noida also available. Will appreciate if someone also provide reviews on other projects Ansal Corporate Park, Stellar Business Park, Ansal API, Earth Tech One, Imperia Business Park.
Which of these could prove to be safe and best investment opportunity
