Mtn reaping us off with content charges

ACCOUNT NO.: A ********** CELLPHONE NO.: ********** The above is information that was charged for content charges. MTN is allowing 3rd parties access to our numbers and then allowing content charges to go through our phone. I never authorized anybody to add content charges to my line. Legally MTN can't do this to us. MTN should have informed us of this content charge before billing it is not part our contract. Please people be aware of this very serious issue. I will take legal action
