You've been very brave coming back on here and letting people know the outcome of everything.
I agree with "Bev"
Well done,to you,for letting us know what is happening {and,quite
honestly,shouldn't be happening!!!}

I,too,would advise you to call the police,as soon as possible
They,I'm sure,will take this VERY seriously. You've got more than enough
evidence!!!
