Probably not the right place but would be interested to hear what anyone else would do.
Neighbouring property to ours is an HMO. I'm not sure how legal or not it is but it is extremely run down and never looked after.
The last few months, the neighbours have started collecting commercial waste and there is just this huge mound of waste which we can see from our place but is also causing damage to fencing separating our properties.
Can't get anything out of the neighbours themselves. Have obtained plans from land registry and tried to contact the freeholder - who has ignored me. Tried calling the letting agent who was previously involved in letting it - he was deeply unpleasant. Have left a complaint with the council - that'll take months to come back, have called environmental health - they referred me to an anti-social behaviour section of the council who won't pick up the phone. I've emailed them but no idea when / if I'll hear.
I have no idea what else to do. Picture attached.
