Vodafone India — Automatic Supermodel Club Subscription

Address:

New Delhi, Delhi, 110045

On 18 Dec, 2015 at 9AM, My balance was deducted for Super Models Club automatically without my request. I spoke to customer support and she told me that the request was from internet. In the meantime the call was stopped responding, after few seconds automated/prerecorded call start. I want to know how that subscription was subscribed without my knowledge. I did not get the satisfactory answer from the customer support too. I installed MyVodafone app and sent complaint but I did not get any status of that email too. How I can track my complaint through MyVodafone app? In my last 5 deductions (took screenshot from mobile using MyVodafone app) there is no such deduction too.
