Ok so for the last two weeks, I have come home and discovered items in the house that do not belong to us. First a glass and this week a mug. Never seen them before and we have only lived in this home for about 18months. These incidents coincide with the day the cleaner comes to our home and we leave a key out front for them. I have spoken to them and shown them pictures and they do not recognise them as items that they have brought in themselves from home. Has anyone got any advice or suggestions about this please? It has really panicked me that a stranger is entering our home.
