Vodafone — without asking you activate a 'zone pack' on my number and deducted 110 rs!

Address:

208005

First a sms comes saying 21 rs has been deducted cause of the activation of some "wwe zone pack" and then when i text stop on the given no. They don't reply to it. No deactivation!!! And then you deducted 90rs. For a freaking monthly thing i didn't even ask for.
I want my money back. My whole family has been using vodafone since like forever. This is so disappointing!
