PLAYSTATION WONT SIGN IN

Was just wondering if anyone else was having any problems with logging into PSN on their PS4? Mines has been down at least 2 weeks maximum and sony arent doing anything about it. When i go to sign in it just says "please wait" and doesnt move what so ever. Also before i swiped my PS4 it said "You must sign into PSN to use the online features of Sony"

Anyone have any ideas whats wrong? Or what i could do to sort this?

Thanks
