Not able to access all my website including cyberpanel

I am not able to access my cyberpanel along with my all existing websites. I can see all my website deleted automatically by cyberpanel service provider. I don’t why they have done this. first, I’ve contacted my own vps machine provider, they said that we have not done anything wrong, it’s better to contact cyberpanel serrvice provider. so I came to here to know wht’s the reason behind it.
