getcanada ji,
Massage posted by u the other day suggested that Chc, New Delhi, cross checked the genuineness of the testimonial from the Univ.which had awarded u the degree.
Since it was only the College which was contacted for the verification,matter is relatively easier to sort it out.
Now, u may write to VO in a very soft language ,under reference to their letter, enclosing the certified copies of letter/email written directly by the college.
Hope, this may suffice VO'S clarification.
Good luck nd May God bless all !!!
