Vodafone India — PostPiad Connection

Hi i had a postpaid Vodafone connection number [protected]. connection was suspended on June 06th 2015. but Vodafone is generating bills in my name unnecessarily Vodafone simply loots its customers. when i raised complaint in Vodafone care they responded that they generating bill on pro rata basis, when the connection itself suspended what is the pro rata basis I need justice over this.
