Dear Sir,
I am working on third party payroll in A company , at the time of joining company gave me appointment letter of third party , now i got new job on company payroll so i need experience certificate but company provide me experience letter on third party's letter head , even they do not mention company name in third party's letter head , new company required something so they can satisfied that i worked with A Company ,what should i do?

How abouty payslips, Salary credited by company's name, any physical documents on which your name as well as company name is specified.. You can also provide your HR contact detail;s for verification....

Dear Mr. Raviprasad try getting someone senior from your ex company to endorse your skills or refer you or congratulate you on your new job.Hope this works.
