Telkom mobile account in a mess for over a year

How can this matter be resolved ASAP? There has been numerous issues with the accounts and nobody is willing to assist. The service is terrible. When we contact customer service, there is no customer service provided. It's been over a year... Maybe more and still no proper answer.
