I did a house swap in November. When arranging it through our housing association we agreed that previous tenants would take out the shed and decking and that they would leave various things in the house and garden (dining table, cooker and wooden planters for me to put my trees and flowers in) and fix several doors which had holes in. In return I removed decking in my garden and left my cooker in as well as a few wardrobes which they wanted to keep and I would've otherwise gotten rid of. On moving day they took everything they were meant to leave and didnt remove the decking from the garden. They hadn't fixed any doors and left old items in the garden and loft including dirty nappies and a fryer filled with old oil. So there is 'bad blood' there, though I didn't stress it, I just left it as not to cause an argument. I wasn't happy but there wasn't much I could do, so removed decking at cost to myself and my gardens are now lovely. Today my next door neighbour has informed/warned me that previous tenant came whilst I was out on Friday and tried to rip my flowers up and take the planter from in my front garden below my front window. She couldn't take it because I've since bolted it to the wall, but texted neighbour this morning saying that if she comes and unbolts it can she store it in their garden until she can come and collect it. My front garden isnt fenced off, it goes straight onto a path - but there's clearly a lawn there and it's still my garden. Maybe she thought I wouldn't notice, maybe she thought it belongs to her so she can do what she wants? It is my property! I'm completely dumbfounded.. imagine if somebody came into my back garden and just started taking my son's toys? I want to text her and say if she tries to remove property from my garden I'll call the police! But have been advised against it in case I provoke anything. AIBU to be fuming?!
