How does a week work in REAL life??

I am SOOOOO sorry that I did not check out TVGC on hello peter and other social media websites before I started my membership. What a joke!! Every time I want to make a reservation there is a story or issue. Latest: Week runs from Friday to Friday and a weekend from Saturday to Monday How on earth does this work?? In all the time I have membership I think I've used it 2 times (for friends) and it honestly feels like I am throwing money in the water. On other websites the same places as yours have availability, but you don't? Really?? I don't get that. I don't get this group
