Hello my name is ***** ***** I will help you with this.
Is there any evidence he is running a business?Alex
Ok - well you dont need to worry. Its not your responsibility, you are not liable for your tenants.
If the neighbour has an issue he needs to take it up with the tenant and inform the Police if anything illegal is happening.
In any event if the neighbour is causing a nuisance he can report it to the Council and they can investigate.But its not your responsibility
Can I clarify anything for you about this today please?Alex
Do you have a number we can chat on?
Yes of course, sadly there is not much you can do about this person complaining.Alex
