Robux and robux chests not availible

Hey guys i recently discovered that the robux and the robux chests are unavailble does anybody know why?

xdalguien sabe como conseguir robux?

wait
what in here don't give robux

im so sad :(
why im go here

I think they are not available because they are going to remove the sale , all the other chests that are selling for a cheaper price are also unavailable ! Just a theory !
