MTN Refusal to assist with idea

I've been trying to get MTN to listen to my idea but they just ignore my emails so I will do my utmost to develop my USSD code myself and hopefully they won't try and ***** my idea since they refused to listen to me for the couple of years. I truly believe that my idea will be of great benefit to the South African citizens and also generate a significant amount of revenue, however, MTN isn't interested and I respect their unwillingness to assist me in developing my idea. I would therefore also expect MTN to respect my idea once it is up and running.
