I got an RFE regarding employment verification.

  6. Organization wise experience

    e) 5th Org - 6 months
    f) 6th Org - 5 year 6 months

I have submitted employment verification letter of 5 Organizations with all my roles and responsibilities mentioned.
I couldnt submit the letter for 3rd Organization as it was a small company and its server crashed and data got wipped out. Its been long time and no one knows me there by face or name. The company HR refused to issue me that letter.
What are my chances of approval?
