False adverti*****t

Cell C keeps sending me sms promoting 50 min to any network for R10 then it says dial *109# then select voice I have looked for this option on both my prepaid and contract line and cant find it, i even called cell c and no one knows about the promotion, the sms is as per below

""Get 50 any-net minutes (valid until midnight) for R10 with Call 50! Dial *109# and select Voice. Buy today! T&Cs apply. Cell C OptOut *147*385#""

Very irritating i had to say
