Dumped Neighbour's Waste At Their Front Door

[headshots]

I've been unlucky with the kinds of neighbours life has given me.
A month ago, neighbour a few doors away came to take my bin from my front garden, placed it in theirs and filled it with their waste.
I went to pick up my bin from theirs and emptied their waste back into their own bin. I knocked on their door and asked politely that they stopped taking my bin (this was the second time) as that leaves me with no where to put my own waste. I made my point and walked away.
To my surprise, my neighbour has done this again today, making it the third time.
They filled my bin to the brim while theirs remained empty. They seem to be producing a higher level of waste as a family and think they have a right to take my bin. What they do is fill mine up first before considering filling theirs.
This time, I emptied their bin bags right in front of their door and took my bin away.
AIBU?
What else could I do to make my neighbours stop disregarding my boundaries. They skip their next door neighbours but come to my bin perhaps because I live alone, look familiar and can be disregarded?

They are in bin bags. There was no waste flying over the place. When I was emptying the bags. They peeled through the windows to see what's going on and left me to it. When I went back out about an hour later, they'd packed it up into their own bin.

Thank you. All very useful advice. I got have arranged for CCTV to be installed this week, just because I don't feel safe alone and around these many unkind neighbours, but now see it will help with other issues.

Sorry I misunderstood. When you said I emptied their bin bags right in front of their door, I thought you meant you emptied the actual bin bags, rather than just taking them out of your bin.

I am sorry this is dreadful - if you can't find your bin I would personally take their bin and stick my address on it.

Thank you for this suggestion. I will look into it. I don't know much about selling or renting out as I'd wholly set out to buy and live in my house but that's become impossible.
I now have it on market to sell through an agent and also speaking to them about finding a short term lodger pending my when it sells.
I'll contact the council about renting or selling to them and weigh my options. Thanks.

That is honestly so so weird, your neighbours sound awful . I would keep it in the back garden.

They are jealous, OP. You have my sympathies. They sound awful.

Well if they held my bin to hostage again and I was without a wheelie bin I’d just empty all my household bins on their doorstep without the rubbish being in bin bags. I’d really give them something to call me crazy about!

I love that you did this!

Well done you!!

Hats off to you OP. Cheeky fuckers.

This is harassment and you should report to the police.

Have you a back garden to put it in?

Yes, I have a back garden and have now put the bin in there. And I'll start to keep a log. Thanks!

Sorry NC fail. Still OP.
