Airtime Getting Cut without subscription

Hello Peter,

I am a Cell C prepaid customer. Today suddenly i got an SMS from MOBTHUMBS that I have got subscribed to them and they have dedected R20 from my airtime. (Which is a per day charge)
I dont even know this service. I did not subscribe with them. Need to get my airtime back on my prepaid account.

Please advice on this.
