Sorry, I'm all for reporting flytip and regularly do but isn't this a waste of council's time? Couldn't you just move it yourself or someone you know? It'd be a lot quicker aswell.
I thought I would report it while I was there. If the council can’t pick it up that’s fine. I’m not bothered. However I think your response is incredibly unprofessional. If you don’t like this app then I think this is an internal issue and the council should reconsider its usefulness. It is not the users fault.
