Dissatisfied Mweb Client

I am very disappointed with Mweb. I received a message stating that my debit order payment will be moving from the 25th of each month, to the 27th. I did not authorise this change and if authorised by Mweb, the change does not work for me. As clients, we select certain payment and debit order dates for a reason - they make financial sense for us. This doesn't and I am appalled at the customer service.

I have been trying to get answers from Mweb and started a live chat with one Nawaal and a Zandile Mani, both of whom I detailed my issue to on the live chat feature but both ignored me on the live chat after my first message detailing my issue and ignored all my further messages. Appalling!
