Disgusting service

The service is disgusting! From the call centre agents up to the team leaders. They are so unprofessional. A paid up letter was emailed after exactly 5 months of me calling everyday to request this letter. A month later after I had received the paid up letter I was told that I owe an admin fee of R116. I called the call centre to query this. I asked this agent how do you send a paid up letter if there’s still money outstanding? What does a paid up letter mean? I got annoyed by this whole thing and because I still had their banking details I made the payment right away. 2 weeks later I received a SMS once again stating that I am owing R200. For what now? These people are ******** and they loot money out of people.
