They still annoy me !!!

I complained last week about the excessive number of promo SMS's that MTN are sending me.<br> I received a response from MTN to say I had been removed from their distribution list.<br> Guess what ???<br> I'm still getting annoying and irrelevant SMS's on a daily basis from this 'outfit'.<br> I'd like the mobile number of the head of marketing so I can send him/her useless messages at random.<br>
