MTN Worse Service Provider

I've had bad experience with the other two big service providers but difference between them and MTN is when there's a complaint they go extra mile to resolve it. MTN is by far the worst service provider ever, I have complaint on hello peter before they never bothered to respond, I've complaint on their complaints email address still have not responded simple because I have terminated all the contracts I've had with them and now I'm nothing they treat me like trash. I will not give up until they pay me all the money they owe me I will post complains everywhere, all social media, radio and news papers I want everyone to know how *********** and unprofessional they are. Before I cut all ties with MTN I will make sure that even their CEO knows how filthy his/her customers are being treated.
