A company called robo silicon came up robo sand in Bidadi, Bangalore. I thought to use it for my building. I visited their site.

There is enough information to contact them through email and phone.

I tried sending email to almost 5 email ids provided in their site , all got bounced.

Called two land phones, no one picked and one toll free number as well.

There is an option to send enquiry from the site. The submit is not working . I checked its source code, There is no action mention to do for submit button. :-)

At last I tried finding dealers information, But no info provided.
