Vodafone — Vodafone vas services has been activated 4 times in last 10 days without my knowledge

Address:

Chennai, Tamil Nadu, 600113

I have been using Vodafone postpaid number [protected] since 2015 Feb, some VAS services have been activated without my knowledge in May 2016, I have called customer care and got refunded at the time of first 2 service activation but I didn't get any refund amount of last two service which have been activated on 23rd and 28th of month may 2016. Once again I have called to the customer care a lady picked up the call and told me that she don't have permission to refund the amount after deactivating 2 times in a month. I am asking you that if you activate 1000 service * 90 rupees in a month then should I need to pay 90000 rupees? . Please don't cheat people like this.TRAI should be strict on activating VAS service without subscriber consent. . PLEASE HELP ME TO RESOLVE THIS ISSUE.
