Vodafone India — unauthorized plans added

Vodafone has been activating random plans on my number without my authorization. They clam that i have activated these via websites that they refuse to name. Completely hollow claim on their behalf when they cannot provide proof that i activated them or even give me the names of the websites from where they claim i activated these.

I can only imagine how many people have been duped by them in a similar fashion. At least i immediately called them and sorted the activation issue, many may not pay attention to the activation messages and would be charged for services they didn't ask for.

Even if there are websites out there which accept request for phone numbers to add services, shouldn't there be a verification otp sent to that phone number to confirm? Pathetic from vodafone, they seem to be running a big scam! No other way i can describe it!
