Business Bank card facilities down for over a week and still no resolution

I have always been a huge supporter of Mercantile Bank, however the last week has certainly left me with reservations. 26 May you were unable to process online credit card payments, 27 May your entire system crashed and it was impossible to log into banking on the app or online, 28 May you run "maintenance" on your system which causes the entire credit card side to collapse. It is now a week since your so-called migration to the new non-working system where YOUR CLIENTS are unable to process payments or transfer funds to / from their card accounts, we are unable to draw statements and the same message is reflected that you are working on it and you apologise for the inconvenience. You are a BUSINESS BANK and this has all occurred over MONTH END leaving us unable to transact - WHEN IS THIS GOING TO BE RESOLVED SO OUR CREDIT / REPUTATIONS ARE NOT IMPACTED ANY FURTHER?
