No access to Sanlam portfolio

As a pensioner, I need to check my investments every month. I have most in Glacier. It is extremely annoying that Glacier cuts off my access to my portfolio, at the close of business on the last day of each month---18 hours for maintenance. ?? None of the other investment houses that I deal with, do this. Do your maintenance mid-month or late evenings, like the others, and stop annoying your customers.
