Annamalai University — transcripts unstamped and no response to multiple emails

I received my pg diploma transcripts envelope after proper application and due payment.
However, it was not stamped and not signed, as per world education services (Wes) requirement.
I called the university helpline regarding the same and was advised to send it back along with wes reference number.

I speed posted the same (Ref no. D991m0675661), delivered on 28th aug'18. I also attached the wes reference number document with it.
I also mentioned it was urgently required during every conversation i had with the officials.
Thereafter, i have called and mailed multiple times but have got no response, nor the transcripts.
I need the same urgently for the purpose of evaluation and have tried all means to reach the university phone numbers.

Request you to please look into this matter on an urgent basis and help me with the transcripts at the earliest with proper
Sign, stamp on the flap join after sealing envelope, as the same is required for purpose of wes evaluation.
