Membership Fees?

My mum recently had R120 deducted from her prepaid total. She was informed by MTN that it was a membership fee of which she DID NOT sign up for or agree to. This is absolutely a pathetic display from MTN to rack up more money from their customers. Is this membership fee going to the \Help MTN Pay the Nigerian Fine"group?<br> <br> Return her money and stop taking advantage of elderly people in your nonsense marketing campaigns and signing them up for stuff they don't need.<br> <br> SIES!!!"""
