BAD SERVICE FROM MALL OF THE SOUTH

i did an upgrade application at the branch in Mall of the South on Saturday the 9th of April 2022. the application was approved but the consultant had issues checking out the application. she said she would log a call with the MTN IT team. i called on Monday the 11th to get feedback but was promised DEborah would call me back. she did not call me back at all. i called again on the 12th at 9am, i was told she stepped out but she would call me when she gets back. its been over 2 hours but no feedback. if mall of the south no longer required to assist me, rather let me know so that i can get the application done elsewhere. i am very upset because they are not even taking my calls anymore
