Resolved I cannot buy anything this weekend and Helpdesk not working for me

I know there is a help desk section for this kind of problem but unfortunately it's not even working for me.

Basically I'm trying to buy a couple of cars but the screen remains like the below when I click on pay....

Tried both in-game and from portal. I have to kill the game from task manager.

PS: I tried from the Web Portal and it worked fine
