Vodafone India — Late activation and then disconnected, still balance remaining

I purchased a prepaid sim on 15th October, they activated after 5 days after several attempts to reach them, and now they disconnected. The last time I used was on 30th 8.40am. The number is [protected]. On 31st night I complained. The agent said it will take half an hr. But no use as usual . Still can't make or receive any calls or text a msg. Ajitharani ravindran
