Hello what have they said to your employer?
how did they know your employers identity?
ok that's strange then, what has your employer said about this?
They have absolutely no right to harass you in this manner. I would suggest you email to say that if they do not stop all contact you will consider taking legal action against them for harassment and potentially for negligent misstatement or defamation if you end up suffering a financial loss as a result of their telling people you owe them money which is untrue.
Is there anything further you would like to know about this?
Hello, for some reason this question was locked for a while and I was not able to see your follow on question. Would you still like help with this?
have you asked them to stop contacting you/ your employer? If so what response have you had?
Well there are 2 options, you could contact the local police and say that you believe you are being harassed contrary to the Protection from Harassment Act and ask them to investigate. It may be that the police consider this to amount to a civil matter due to the way that it originated but they may be prepared to be involved.
If they are not then you you could consider a solicitors letter threatening them with action in the civil courts. If you have household insurance then it may include some legal expenses cover so it may be worth looking to see if your legal costs could be covered in that way.
