Poor and Pathetic Service by SUPERSONIC FIBRE (MTN)

I am totally disappointed with the service i am receiving from Supersonic My phone line has been down for the last two weeks , every time i call the call center i am put on hold for at half an hour. A technician was assigned to come out to my house on Tuesday the 16th of November , to date he has not called or come to my reisdence,I have sent numerous emails to the supervisor Bonke , received a reply to say he is investigating my case and will get back to me. Service is pathetic I will advise not to use Supersonic going forward. On a daily basis there are complaints of poor service against Supersonic.
