PF Exposed Closed Company: How To Clear Background Verification?

Left job in 2008 after 14 years of service and till then i was registered in PF and got Pension eligible certificate after leaving service. As per the certificate i was eligible for pension from Mar-2025. From 2009 to 2025 have done job in a company where there is not PF account. Now i want to enrol me for pension and Form 10-D is submitted by me. PF office replied my that i have to get the form signed from my employer which is not existed now nor i have any contacts of any employee of the company. After lots of deliberation came to know that the company is wind up few years back and i have no idea or information about the whereabout of the company. Now, my question is as to how i can get myself enrol in pension without being certified by the employer? I belief there must be some mechanism available for getting pension without certified by the employer. It has been more than 17 years i left the organization and now how can get in touch with the company which is wind up. Kindly suggest me with your suitable reply.
