I took jio airfibre connection on 19th aug , paid 2121 for 3 month plan. Billing started from 21st aug and my billing cycle is from 21-20, I didn't pay anything in sep, for oct ₹45 bill was generated but now for oct-nov , they are asking to pay ₹706.82, may I know why I am being charged ? It should be free right from oct to nov? I called customer care and she said it's for 21th nov -20th dec which does not make sense as this is a postpaid connection..also the bill clearly says 21st oct- 20th nov bill.
