Air tel
Unwanted subscription of "daily mix"

I got a message from airtel a few days back describing one offer which I did't even read and deleted immediately. But somehow I was subsribed a plan daily mix and I am getting messages from the number 555630 continuously.

It's not the first time that I am automatically subscribed to a plan which I don't want.

Anyway, now I want to be unsubscibed from this plan.

thanks
