Idp Ielts — Invalid allegation and result cancellation

Dear Sir,

I am Davinder Singh, and my passport number is R0417091, In the attached mail there is mentioned that you have "There is evidence that you arranged for another person to impersonate you and sit in the test on your behalf".
This allegation is wrong and I do not agree with this So I am demanding a copy of the evidence because this is my fundamental right to ask for proof.
I will challenge this matter because I had given the test after proper Security checks and verification.
