Visvesvaraya Technological University — Registered EDDTS with foreign number

Hi there, I had provided a foreign number for registering EDDTS and would want to change that to an Indian number.
I submitted my application for transcripts and emailed the application details to [protected]@vtu.ac.in but did not hear from them. I am trying to register with EDDTS, but the foreign phone number prevents me from getting the OTP. Can you please let me know how to change the phone number to an Indian number or please approve the email I submitted for the transcripts?

A prompt response would be greatly appreciated.
Thank you.
