What a bunch of oiks they sound, well done for sending them on their way!! While my instinct says 'get the b*ggers back', I think the Council are right tho re soil and do you want the hassle of persuing the contractor anyway? Either get a skip dropped round and some friends to help load or ring a 'muck away' company and get them to whip round with a grab lorry. I would think that �150.00ish would be cheaper than being charged by the council. Good luck and put it down to experience!
