Internet banking site and app down for past two nights

Good day, I am terribly frustrated with your service. I have been trying to complete a business transaction which requires me to do an upload online but because of night shift data I can only complete this transaction after 12 o'clock midnight but for the past two days, your internet banking site and app has been down and you don't bother to notify us your clients about it. This is costing me more than you can imagine and I will fail to meet the deadline with my client set because of your unforeseen downtime.

This is not acceptable and it is not a good way of dealing with your clients. You should at least inform us of this downtime so that one can make alternative arrangements.

This is simply poor customer service and a disregard on your side.

I am extremely frustrated
