I-140 Receipt number and name does not match

[Kris01]

I am mentioning my case and query below. I would appreciate if anybody can help and guide me with quick replies & answers..

  My I-140 was approved in February 2001 from my previous company A.

   I recently checked in USCIS web site and it still shows my I-140 in approved status.

   I have my I-140 Receipt notice with me but not the I-140 approval notice.

  I am currently working in India with company B.

   My current  company B  is ready to process my green card and wants a copy my Original    I-140  approval notice for using the priority date (PD).

 My previous company A no longer exist.

I recently contacted FOIA online and created a request to get a copy of my approved I-140. I attached the following documents with the request

1.A scanned copy of my I-140 Receipt notice (Form I-797C)

 The FOIA responded by saying that my receipt number does not match with my name hence they cannot send me the file.

I am very surprised and confused because my I-140 Receipt notice(Form I-797C)  has my name in the Beneficiary column. I am not able to understand what they(FOIA) mean by saying " my receipt number and name does not match".

Is it possible that my I-140 was transferred to some other person by my previous company A?

I would appreciate if anyone here can answer my query and help/guide me in getting a copy of my I140 approval notice at the earliest.

Thanks
