PersianCatLady I think there is a FB group for these people where they swap tips 
I hope your nightmare has gone away. Mine has. People don't understand what it's like.
One of the worst things that happened to me was that at 3am four police officers, hammered on the door shouting that if we didn't open up, they were coming in. We were fast asleep.
My husband groggily asked them to wait until he put some trousers on and they screamed: 'Open up NOW! Or the door's coming in!'
They held him, naked, in a separate room while they questioned me, also naked, in bed. They let me have a dressing gown.
Someone had called them reporting a woman's screams and they'd come to save me. I don't blame them and neither did my husband, once they let him put his clothes on.
It was a malicious call and designed to bolster the false report of threats to kill which had been reported that afternoon.
People who haven't been through this have no fucking idea of the lengths people will go to harass you.
So, if you don't mind mouldycheesefan, I won't give it a rest. And the OP did discourage people from contacting the police.
The police I dealt with were great and encouraged me to call. I'd rather go with their advice.
No one should ever should think it's too much trouble to call. If the police think it is, they'll soon tell you.
