Vodafone India — I can't pay my bill or port my number

Address:

Kolkata, West Bengal

I am unable to get a porting number from them as they have some technical issue which they are not sorting. I can't make a payment of my bill either for they are showing no dues. But the company is sending bills and has now on the verge of deactivating my number. I have complained and have followed up but they have provided no solution and is only asking me to wait for over two weeks. They are not letting me port to Airtel either and not helping me.
