Vodafone India — Bill payments

Address:

400089

I am the subsciber of vadofone and had made a request to unscribe the number and made the payment of Rs 1500 in the month of October 2015. I too have a request number.later on in the month of november i got a call to pay outstanding Rs 350 which i did on line. I have the mail too of the payment. Then i got a bill again via post, which i did not pay. i immediately called the center where they denied and asked me to pay bill. i ignored again in this month i got the bill, on calling vodafone center they told me to visit nearest centre, which is ghatkopar. They too are refusing to listen to me and asking me make payment. When i told the request number they are saying that it was not a request. What do i do now?
