call centre agent

VERY FURIOUS AND IRRATE. I am very furious. I called MBD to settle my account last week and I was given a settlement amount with I asked for it to be debited via debit order, I was told I need to do a direct transfer. banking details given were not correct. I asked for correct banking details and they were still incorrect. this morning I asked to be called back by Nkosinathi Mtshali, he never called back. I became furious because i have to drop everything i was busy with to attend to his call. i then call their callcentre again to get him or who so ever to call me back. i'm still waiting. Nkosinathi Mtshali was very rude to me. telling me i haven't been paying this account and I'm the only customer saying their banking details are incorrect . The way i got home late last night coming from the mall to depositing this money because the banking details were rejected by my banking app, because I so much want to settle my account. Unprofessionalism is on its highest level. I was never treated this way anywhere else. MBD is actually delaying me of my financial freedom because the negative report will remain on my credit record for as long as they want.
