My Sister having a Vodafone no. and recently she went abroad for her further education. She used that no. for a week and then she stopped. After a month, we in India received a bill of Rs. 9000 from the company. We also got a call for the payment but i requested for negotiation so they agreed for Rs.5000 and accordingly, i paid the negotiated amount. Now suddenly, we got a legal notice to pay the remaining amount.
I trusted them and made a big mistake of neither requesting them to give me in writing nor I have recorded their calls. The only positive thing I did that before making the payment of Rs.5000 I mailed on the executive'id that I am making the said amount as full and final settlement amount as agreed and accepted by that Vodafone's executive.
Please guide me in what way i shud fight this case and as such my sister is out of country, will there be any adverse impact on her?
