Pathetic service and incorrect debit order date AGAIN!

In November MiWay ram a debit order before the agreed date and it bounced. I then complained and one of their staff members named Mawulom Peku promised to rectify this by: 1. Changing the debit order date to run on the agreed date 2. To run a debit minising the fee of the bounced debit order as it was not my fault. Today, when I woke I get a notification that a debit order ran again on the wrong date, the debit order fee was not subtracted and debit order bounced again, me incurring yet another bounced debit order fee. I really don't under how such a well established company cannot just stick on the agreed terms. My credit profile is getting impacted negatively due to 2 consecutive bounced debit orders from MiWay. This is really pathetic now!!!
