Debit Order request not resolved after 2 months.

MTN literally has the worst service ever when it comes to contract payments and debit orders. Changed my debit order bank details in May 2025 for my new bank account to be debited from June 2025 and I asked them to delete my old bank account because it was closed. DebiCheck mandate was approved timeously. Come June 2025, they still tried to debit my old bank account that was already closed, which was plain stupid. I had to go to the branch to pay by myself. The same thing is happening this month. I don’t know how else to explain myself or how many times I have to chase them around like we’re playing Tom and Jerry. If my new bank account is not debited today, I’m going to cause a scene at whichever branch I’ll be going to tomorrow. Watch me!
