First of all, I want to inform you that you should not have left the company without obtaining your relieving letter and experience letter. I advise you to contact your previous employer and request these documents from them. If they refuse to provide them, you can escalate the matter to the Director of the company or any authorized personnel. If the issue remains unresolved, you may consider seeking assistance from the Labour Commissioner (ALC) in your area and explain the entire situation.
Please let me know if you need any further guidance or assistance.
Thank you.
Regards
