so 3 months ago i opted for static ip connection and now i want to cancel it but yesterday when i spoke with the customer care they said my account didnt have any static ip connection and that it was already on dynamic ip, but i told them i was getting charged for static ip from last 3 months to which they just said call us when the new bill will be generated for the waivers and that i wont be getting billed for it from next month but i am still configured on a static ip connection. what should i do?
