Trai — upgrade the plan without my consent

Address:

New Town, West Bengal, 713336

I am resident of Jamuria and using the vodafone postpaid connection. In this connection my plan was upgraded without my consent wand when I call to the customer care he said that in earlier plan company get loss so they upgrade the plan without any customer consent. I had also written a mail to them but they are saying that you had pay the upgraded plan bill and also disconnected the connection. My Mob no is [protected].
