Consumer Redressal

I took the number 9819426967 in Mumbai and used the same between January and March this year. I am back in Kolkata now. I wanted to retain that number. I was told by Vodafone Customer Care to pay Rs 300 for safe custody. I have paid Rs 300 in two instalments on 8th May and 15th May . I called up Vodafone Customer Service on 15th May and I was told that the temporary suspension would be activated within 72 hrs which did not happen. Again I wrote an email to them on 31st July 2013 which they responded to on 2nd August 2013, stating that they have not received payment of Rs 300/-. Copy of the mail given in the attachment. I connected with a Vodafone agent over chat. He also promised that the safe custody will be activated within 8th August 2013 (gave me the request number 1385244910, copy of the chat transcript attached). Nothing has happened since then. I am ready to pay the bill upto the period of usage after deduction of Rs 300.
