By mistake I have called my sim card in russia , I am living and studing there , I was on vacatations in india , by mistake I have dialled that international number , the number was switched off but they cut off my balance , I got shocked I have called again this number again they cut off money even number was switched off , then I talked with customer care services , he even threating me that arugument with customer care not allowed , this was out of my mind
