This Isn't Meant to be Here

We drove past the block over the weekend to find that our neighbour has been slabbed and that there is a HUGE mound of dirt and concrete on OUR block!  I'm pretty sure this is not meant to happen without our consent, strangely enough if they had asked we probably wouldn't have mind.  We're hoping that they remove it in a timely fashion because we don't want it to interfere with our build and cost us money to remove.  So I'm giving them a couple of days and then I'll contact them to find out what's happening.
