Ackermans poor service

Good day i've opened a Ackerman account im not happy at all now this is the second time i experience bad service from Ackermans the first time it was witj the opening of the account. NOW I just phone customer care toe update my address on my account because my address spelling are incorrect so i spoke to Ziki on the 26/07/2022 (8:30) she asked me where did i last used my account card i cant remember i think it was Menlyn or centurion mall just because i fail that question she block my account im sure ther are other questions you can ask to confirm its my account but to block my accounts because i cant remember where i used it the laste time is unreasonable. SOMEONE NEED TO PHONE ME TODAY TO CORRECT THIS I WILL SPREAD THE BAD EXPERIENCE ACKERMANS GAVE ME
