BSNL — mobile usage fraud

Address:

Vellore, Tamil Nadu, 632002

Hello,

I received an sms from bt-bsnlcg stating "your pack dil dosti chatting (54000*) is due for renewal of[protected]. It will be renewed for 3 days at rs 3.0. To unsub sms stop or call to155223 (Tollfree)."

It came from the message center : 91-[protected] on 8 oct 2019 08:35:21

However, i absolutely did not subscribe to dil dosti chatting and have never even heard of it. So they have deducted rs. 54 from my airtime fraudulently.

I immediately sms'd the sender that i had never subscribed and to stop the subscription and i also called the number listed and did the same.

But from reading the internet, i see this is some kind of fraud and even after saying no, people are having money deducted.

I demand that bsnl unsubscribe immediately, show me who subscribed me and refund fully the amount (Rs. 54) they took illegitimately.
If this is not done, i plan to deactivate my phone fully and never use bsnl while publicizing this scam as much as possible on the net.
