Vodafone — proper information not provided before payment

I recharged vodafone account with rs 347, which is free calls and 1gb data per day for 28 days. I recharged through paytm. After recharging the calls were not going, after calling the customer service, they told that the service will not work when under roaming as my sim is under tamil nadu and i'm currently staying in bangalore, karnataka. But this information was not conveyed before recharging.
