[Resolved]  Airtel — ZONG facility

Address:

Bangalore, Karnataka

Hello.I use the zong facility in my airtel phone to make online payments.
But yesterday while upgrading my membership in a website using zong, the process couldnt be completed.
Everytime i texted ZONG to the number specified, Rs.3 was deducted from my airtel account.But the actual payment didnt happen and i couldnt upgrade my membership in that website.Today when i try again it shows 'spending limit reached'.I dont have a credit/debit card to use.
So please tell me how to increase my zong spending limit in airtel account.
