Possable Hacked / Stolen account Help Please [NSFW]

Hi I hope the WordPress Staff can help here.

I have a domain HERE [VERY NSFW] & it’s been totally fine till now.

I came to log in & WordPress gives me an error. so no matter what I do, I can not log in.

So I request a password reset. By User-name, but I do not get no email.
So I try request by email Only to be told ERROR no such user exists.

I called my hosting & there is nothing they can do, as it’s a WordPress issue, they advised me to come to the forums & ask for help here.

But I’m not sure how much to mention in an open forum since this is a security issue & I have to give out my User-name & email most likely.

Can someone advice me whom I should be contacting about this issue or is there any Phone Numbers for England I can call so I can sort this issue out & get back into my Account / Website.

Thank you in Advance to anyone that points me or helps me regain control of my account..

Gary
