Idea Cellular — Unnecessary deactivation of my sim

My sim is deactivated without any reason only in this month I had recharged rs 50 instead of regular packs...do idea or VI need rent for using sim cards now ...is this the way they provide service to your old customer...it was not even like my sim was not used for 3 months or more ...so do you people directly deactivate the sim of alternative customer for fun... How trouble some it can be for a person if you deactivate without any reasons...is this satisfied service...if so ...then I don't have good feedbacks even after been an old customer of idea ...
