************ marketing strategy ignoring a do not contact directive listed on the direct marketing association

MTN after I expressly logged a do not contact on my contract and after repeated requests to stop sending me marketing material have decided that they can simply ignore a do not contact listing on the direct marketing association and continue to send me their garbage against my express and direct wishes. The business arrogance of this useless company is astounding. Your clever little attempt to re activate your ability to make contact with me by sending me a one way message without the ability to opt out borders on questionable business practice which has become the hallmark of one of the most ************ businesses in Africa. Please leave me well alone and maybe concentrate on sending my bill to the correct address which you haven’t been able to do since I was sadly migrated from auto page cellular, a company 500 times better than mtn on their best day.
