Such shocking service, it is scary!

After 4 months of to-and-fro with Mtn, I still do not have a resolution to my bundle being loaded incorrectly and this month it is even worse as I also did not receive the allocated data! The reply on Hellopeter from Zenetta Portia Viljoen (Complaints Management Team) saying she would give me feedback has not materialized either. Where to from here???
