Idea Cellular — regarding deactivation of my idea mobile no [protected]

Address:

560066

My idea no [protected] is deactivated after 2 years of service without any reason. I have visited your store at Brookfield, Bangalore 2 times. Every time I visit I was given a new sim and I was told no will get activated next day. But it is still not active. I also called customer care. There is no satisfactory reply.
