migration is impossible

End of November I requested migration at Westgate store. Case number ***3. Nothing happened.I went in store again on the 17th of December case number ***5. Up till today the migration has not been done yet. I want to migrate from unlimited @ R 899 pm (this unlimited is limited to 100GB per month-after using 100GB you are not able to use the internet) Migrate to 100GB day-100GB night at R999 pm R100 more per month! Speaking to Telkom consultant today I learned that no migration fees were involved as I go to a more expensive package. I have to go in to the store again! I just like to know the following: Who is able to do the migration. as neither store nor call centre can help me migrating?. Who do I need to contact? How often do I need to phone or go instore for the same request? 6 Weeks later and nothing has been done. I am been send from pillar to post endlessly. Not impressed.
