Bad business practices

Ref: MTN REQ:***.<br> In May last year 2015, MTN ported out my *** number without my knowledge and they gave it to someone. When people try to phone me the would get someone and they were insulted at. When phoning Vodacom, they told me that the number was not in their network anymore. I then phoned MTN and they returned the number but it was for few day. And they ported it again. When complaining they brought it back but all MTN subscriber are not able to reach as they are told that the subscriber is to available in the MTN network. I have tried it myself. I don't have to be in the MTN to be accessed. I lost 3000 point in the process, the third party viewed my confidential information like banking correspondence etc. May MTN please release my number. I'm entitled to this number, its my right to have chosen so. I talked to MTN and above is my reference number. Please help or I will ,have to go legal. Thank you, Moses
