Airtel — not able to recharge by paytm after porting

Address:

Gandhinagar, Gujarat, 382028

I recently ported my number from Idea to airtel Gujarat .since the day it got activated, i am unable to recharge online through paytm app. The transaction gets declined in both the cases without any reason.. I tried recharging other airtel numbers and they all worked fine. I would like to request you to kindly look upon this issue and fix it as soon as possible.
