Unable to upgrade for 2 months for being "deceased" on MTN's system

Unfortunately there is not a "no star" selection:( Have been trying to upgrade for over 2 months with no success. MTN have had me run around to sort this out myself via Home Affairs and their credit vetting agency - XDS, who also had me to try and find which one of their service providers had me declared dead on their database (Still awaiting for Kemala Premlall from XDS for feedback on this, although they eventually did declare me as alive. Have spent more than 4 hours holding on for various MTN/XDS numbers (have on most occasions been referred back to 135), being cut off, no managers ever calling back but got told this morning that 135 cannot help me. So a very unhappy MTN client. Can anyone at MTN help, as it seems that they cannot/are unwulling to do so.
