Vodafone India — Regarding disconnection of my sim card

Address:

Thane, Maharashtra, 401202

I converted my prepaid plan into postpaid around 2 weeks ago.. It was done through vodafone business associate. I called vodafone customer center they are saying that my sim is active but in my phone the sim is still inactive. I went to vodafone gallery regarding this issue they said the sim which was given to me was registered under another number. i called that associated many times he is not picking up his phone. As am a working guy i dont have time to visit the vodafone gallary. As my sim is active i have to pay bill even tho am not using it. so i want to disconnect my sim card wid vodafone my number is [protected]
