Stop vandalising my intercom, gate and property

I live in Parkmore. Every few days I drive up to my home to find an unwanted K&N Gate Auto sticker on my intercom box, gate, or outside control panel. This is vandalism and illegal advertising: K&N Gate Auto has received no permission from me to advertise on my property. As soon as I remove the sticker, a new one appears several days later. I don't know who you are, K&N Gate Auto, but I will NEVER use your services. So stop coming onto my property and attaching your adhesives. If I catch your representative I will call the police immediately.
