Tell letting agent you tripped over the rubbish they left and you will be making a claim for compensation
I all seriousness I now would just go on a passive aggressive blitz with these builders. Lots of keeping space in the road for a friend (who never turns up). Also chuck all your own rubbish in their pile (take out identifying items) When a delivery turns up, choose that exact moment to take your bike out etc. Ask them to shift the rubbish so you can get your wheelie bin out everyday
On behalf of all the respectable middle aged tradesmen on here may I apologise that you have been treated in such a manner. There's absolutely no cause to be rude or disrespectful of anyone. We're not all like that. It makes one wonder about the quality of their work as well. Tossers!
