Back on point although she is advertising Monday-Friday she wasn't available last Friday and didn't log on on Monday.
Those that know her well it might be good to suggest she puts up dates she is available.
My understanding is Louise generally works Monday to Friday (although not every day of the week) and occasionally on a Saturday (for pre-bookings)
When I see her next (& I'm lucky enough to see her often) I will mention that she might want to put her availability on AW.
However, I also do know that she is not the most techy savy, so this is unlikely. She only rarely updates her AW profille and pictures for example.
I would keep texting her or WhatsApping her and she will get back to you eventually.
Although, as others have said, be aware she is VERY popular, is good VFM and offers an excellent service, so she will be Busy.
Keep trying and Good luck MrBenn
