I beg to disagree with you on the point that it is mandatory to visit Paytm's KYC center for completing one's KYC with PayTM. I never visited any Paytm's KYC center. An executive from Paytm came to my office & I got my KYC done at my office only.
When you talk, you are only repeating what you already know. But if you listen, you may learn something new!
