Vodafone India — outgoing blocked in spite of making payment

Address:

Chennai, Tamil Nadu, 600094

I had taken a vodafone post paid connection in my wife's name shruti. The mobile bill to be paid was 700 of which i made a payment of rs 500 on 23/11/17 and 250 rs on 26/11/17. Vodafone said they received only 250 and not the 500rs. I mailed them bank statement showing debit and still they have not updated my payment and have cut my outgoing calls. They have also not reversed my payment. I sent them a screen shot of my payment and the payment is showing as successful.in spite of making payment they have not updated or refunded and they have cut my outgoing also. It is 10 days since i made payment and no solution is arrived.
