Dear Mr/MS Kaushal,
After going through your last note, I am surprised why you are worried so much about this person may be you had some very close relations with him now fallen apart. So when you have written to his employer and they have no objection with his fraud or wrong doing, then what any body can do, if it's a Government Company you can go to court for the impropriety but in private sector it depends on the Management of the Company, and theycan hire any one whom hey like and no association can force them to remove any employee. So if you have only one target in life to take revenge from this person for the hurt he has given to you find some legal grounds and file a criminal case against him. Otherwise just forget it, In India there are lacs of such people who had taken or were forced t take this type of step to carry on the career and progress.
Please learn to forgive people for their mistakes and that will give you peace of mind and let you grow in your career. And be sure this type of person will get caught some day for some of his mistakes. On other hand please understand to live a normal life and grow in career one must have calm mind and if you have calm mind you can grow fast otherwise you will just going on finding faults in others. These experience certificates and BG checks can just give a break to any one but no one can grow in career without performance.
With Best Wishes.
