changing of debot order dates

Good day<br> <br> Was called today by a consultant cause my debit order was returned, I have four lines that have been going of on one debit for months. Why do you split it up without notification. Apart from the pain of paying in on a suspended line, bank fees and embarrassment. This is totally unacceptable<br> <br> Doesn't help to call customer care cause they cant deal with upset clients
