African Bank poor service and lack of customer service

i called African bank with regards to withdrawal of my money on my 32 days account, which on the 6th of March 2024 i called to log a notice of withdrawal as per the standard terms and procedure which then i received a notification of the notice of withdrawal which then stated that ill receive the funds on the 8th of April 2024, the funds haven't reflected, i then called African bank and only to received poor and inadequate service from consulted named Tlalemi who was rude and dismissive on the call with no customer service at all whom told me "I've canceled the notice" which was not the case and they had no records of the fact. so i am asking you to intervene so i can get the funds. I once had the similar issue last time which was promptly resolved by the supervisor which i also ask Tlalemi to refer me to as she was *********** to assist me and she refused - i want my money and had high expectations from African bank to have a seamless process of banking which i am now experience horrible service
