Vodafone Telecom Services — Fake bill charged to my account

Address:

West Delhi, Delhi

I am Namit sharma, was using Vodafone services on the number # [protected] till 25 feb 2011 then I port my no. to Airtel after making last bill payment which was 1264/- (My Billing cycle was 19th of every month) and I paid 1300/- on around 21st of Feb. (Rs.36 extra). then my no. was migrated in Airtel....so basicly i am suppose to pay for 5-6 day to Vodafone.
But today I got msg saying 'ur Voda bill is due pls pay 1976/- to avoid the suspension of services.'
Then I called to cust.care they said ur nov.-10 bill is pending, this was really a pathetic nd shocking movement for me...coz I have been paying the bill always no bill was pending on me. This is just a Common sense If i wudn't have made the payment so how was i using the Out going nd Incoming till 25th Feb (even after more than 3 months) and let me bring in ur knowledge one thing if v didn't clear our outstanding v can not Port our number its as simple as that....its just the matter of common sense..
I request you to kindly solve the issue ASAP and arrange a confirmation call against that.
I'll be really thankful for u.
