Clueless MTN personnel on who's doing what

For the past couple of days I wanted to migrate from one package to another after I was told by MTN personnel that I can but I'm being send from one place to another, Thursday I was told I must phone the *** number, doing so they told me I must phone 135, I only had chance on Friday to phone but they told me again I must phone *** or go to a store to do so, so on Saturday I went to Bay West mall in Port Elizabeth on the bottom floor but the personnel was so unhelpful and slow and then told me I must phone *** on Monday today, I did and the was told to phone 135 by the personnel, 135 told me again I must either go in store or phone *** as they don't have the forms ect. What the hell is going on by MTN as nobody have a clue who must do the migration, someone please help as I'm not going again to PE or Port Alfred as I'll be wasting a lot of fuel.
