Easy Equities ignoring potential account theft.

Can someone please get Easy Equities to assist me.

My access to my account has been removed and Easy Equities says my account does not exist.

This is a long-standing account and I have a substantial amount in my account and have not slept for over a week.

Easy Equities just closes a ticket if I open one.

I am getting quite desperate with their lack of assistance in such a serious matter.
