Question to all the Dog Owners

I usually take my dog out for a walk twice a day(morning and evening/night). I also carry poop bags & make sure I pick it up whenever it poops. Recently I’ve had a lot of problems with my neighbours regarding this. Even though he poops on the platform near their property(not in their property),they seem to have a problem with it. They want me to go somewhere else,but he doesn’t poop anywhere else than in the street I reside in. How do I deal with this?
