Why wont you let me spend money with you?

I have been trying to upgrade my line ***) from faster to fastest line for almost 3 weeks now with no luck... I have been to Telkom Menlyn Mall store on 1/12/15 to apply, then again on 3/12/15 to ask why it has not been done and then again on 6/12/15 to ask again why it has not been done. Today is 8/12/15 and my line is still not upgraded. I have to take off work each time for 2 hours just to fin out that nothing has been done yet and that \technical"has not been able to assist yet. More shocking is that the staff in this store agrees with me when I complain about Telkom"
