Incorrect debit order date

Why is it that all along you run my debit order's on the 27th and this month you decide to run the debit order on the 26th. This has now led to me incurring bank charges as the debit order came back unpaid and obviously this will lead to a negative credit profile as it now seems like i'm not paying my obligations on time. Can you urgently fix this as your call center is not helpful, they've been transferring me from one department to the next which is also annoying. Also please train your employees to have good customer etiquette, i spoke to one of the most rude consultants by the name of Nosipho Magasela
