Icai Cds — website issue

Website:

icai-cds.org

I have to update my mobile number & address before ordering books. When i try to update, i am not receiving otp at all. I am trying from 4-5 days. I am pissed off with this. The initiative is good but is valueless if the platform is not good. We, students, suffering finally. Please ensure basic facilities of the website works so that student can order books peacefully.
