African bank is the worst

Every time I have in interaction with this people I wish I did not ever apply for anything with them, and their call center service is so terrible its unbelievable that its even allowed, I have tried a million times now to habe my febit order fate changed, I sent the documemts they requested and every single time the date is not changed and they harass me for payments days later, I have explained a million times that my pay date is the 25th my previous job was the 20th and yet they keep trying to take money on the 20th, they say it can be changed and I just need to send the payslips and they will change the date, I do that and the following month they just try to debit the 20th again. The worst part is the attitude of the call centre agents, I answered my call wondering why they are calling me, I asked how can I help you, the lady rudly saying IM GETTING THERE, naturally I immediately got defensive, she then proceeds with fo you agree that you owe us, to which I said my installement is due the 25th, she then proceeds with thats not what im saying you owe us money, I then went on a rant about how they tried to debit yesterday but my debit order date is supposed to be changed to the 25th millions of time ago, she was so rude I ended up dropping the call. Im so tired of this place, and complete unprofessionalism, they dont do what they are supposed to do, and then treat their customers like ****
