sify account thru internet

Hi, I have recharged my sify account thru internet n i was not aware that line charges have to pay extra to the dealer. Few days back the dealer’s guy came & asked for line charges. I said him that i will confirm from Sify Customer Care that whether i have to pay eatra on not. But the Sify dealer has blocked the access without infroming me. Is this the service you guys cater to the customer?
