Arena closed (PC and mobile)

Ok,first I couldn’t enter shop (windows 10,europe),than from yesterday I couldn’t enter shop and arena from my PC but I could enter from mobile phone…AND NOW I cannot enter neither on mobile phone or on PC!
WTF is wrong with you?! That issue doesn’t last like one day,it lasts for week now for some players!
You are really getting on my nerves now and as soon as I come across some decent other game I will say my final goodbye to you and I’ll be really happy about it!
I WANT TO PLAY ARENA,FIX IT!!!
