Vodafone India — Refusal/avoiding to disconnect postpaid connection

Address:	Bangalore Urban, Karnataka, 560047
Website:	vodafone.in

I have visited their store several time requesting them to disconnect my post paid connection under red plan but everytime under one pretext or other they avoid doing it.and later they call back saying they are giving an offer of holding the account for 3 months on same plan without charge but the internet was disconnected.Afriend suggested i could easily do it on the net but i see no link or icon to disconnect.this is nothing but fraud and cheating. why are authorities blind to this?
