Dear sir my last idea cellular bill was 476.98 and i was paid them 480/- but when we send request to port my number to new operator they add me extra balance 50/- inr & said to me you have my balance that's why we can not port your number. We call several time to help line number & we clarified my detail then he told me by mistake we have added 50 inr. But when we send appellate delhi then he told me "ejected cause of your outstanding amount 46.98 is remain so u can not port your no. [protected] in any operator." so sir i want claim to idea operator. I have all voice recorded to care line number & all payment proof & bill invoice
