[Resolved]  Vodafone India — sold postpaid sim not explaining about prepaid or postpaid

Address:

600015

Got a sim for free on street side stall in chennai saidapet near railway station, the seller didn't explain about the sim type (Post paid or prepaid) instead told the benefits like 2 months free data and calling.

After using 1 month, got a bill amount 375 rs. I stopped using the sim and vodafone also stop servicing it after 10 days (Approx).

Again the collection agents are calling me and asking to pay the money of 880 rupees.

Please suggest me what to do here.
