For company
As there email id doesnot accept mails
There postal address & details mentioned on there site is as follows
{address info removed} (wealthlinepromotersl@gmail.com)
Please tell me truth for this company

I wouldn't. Sounds like a dodgy MLM.

These types of things are always scams. Forget them unless you wish to lose everything you invest.
