Upgrade went wrong....

Poor service from your Kwadukuza Mall store. Went in for an upgrade. Was they they have stock by Seetha. Proceeded with the upgrade which took approximately 45min. At the end was told she has to send for cancelation as the stock on hand did not match the color on system and price plan. Frustrated and angry. Was told by Seetha that she had canceled the upgrade request but today I find out from telkom mobile that the upgrade is still active. Tried calling Stanger branch for 4 hours... Rings and rings... Nobody picks up.
