Dear Mr.Prakash,
I can understand the situation and I am happy that I was part of the Aegis Ltd. for the past 3 months.
Before leaving I request you to kindly do me a favor.
It would be very helpful If you can provide me Experience Certificate of 6 months and the Payslip for the past 3 months.
It will be very useful for seeking job opportunities in future.

Thanks and Regards,

One question - if you're happy to have been part of the company for only the past three months, why would they issue you an Experience Certificate for six months?
