worst bank ever

i blocked my online account when logging in, i then called and was provided a reference number, and was told it would be resolved 24-48 hrs, i then called to let them know it has still not been resolved and my online account is still blocked, i spoke to Ntebo Maake (his the so called supervisor) he said there is nothing on the system showing my reference number he will email the department and call me back the next day, he did not call me back, my query has been going on since Thursday, he didnt sound like he knew what he was doing, i dont understand how he is in charge, i then try to call african bank and no one knew him, i also asked him why do i have 34 months on my account loan but my loan says it ends in 1 February 2021, he tells me to leave it i shouldn't worry, i told him there is something wrong how can he tell me not to worry. i need to speak to someone who knows what is going on not useless people who are in charge, african bank gives the worst service ever, useless dam bank, i cant wait to get my loan done with this stupid bank
