Unable to get through to Legal Department

I am extremely frustrated with the level of service provided by MTN especially considering I have been a loyal client for the past 8 years. Returning to SA I come to find out that I have an outstanding balance and my account is with legal. Having settled the outstanding balance I attempt contacting the 808 call centre, after numerous attempts and my call continuingly being dropped I have found little joy, as I am typing this my call has been dropped yet again. So I finally get my account re-activated after 2 weeks after having paid, then I get told that my main line is not registered with the network and my secondary line HAS BEEN GIVEN TO SOMEONE ELSE. UNBELIEVABLE. Then my contract dates have been reset and now I have to pay a further 24 months before being able to upgrade. I AM EXTREMELY FRUSTRATED AND I NEED IMMEDIATE FEEDBACK!!!!!! DISGUSTING SERVICE REALLY!
