I've never had to do this before so Im not exactly sure what to say. We underbid a lawn in a new neighborhood to get in there... it wasnt by much tho maybe $5. Well this guy has a tree line behind his house so when we estimated we went up to the tree line. Nobody was home to confirm so we cut the lawn. Well after a few cuts the guy tells us we need to go behind the tree line and cut. So we did it the first week and it took forever and killed our schedule. We need to drop this guy since we can't handle the property size. He paid for half a year of service so we have to cut him a $800 check which is his balance after the cuts. Here is another twist. Today we got a flat on one of our machines and were already running behind schedule because of a cut that the customer waited on and we had to clean it up. So we decided not to do the back which grows alot slower than the front and charged him the original price for the front. He called up tonight complaining and demands that we come out tomorrow morning and cut it... we have a full schedule tomorrow and cant do this. How do I tell this guy we aren't coming tomorrow and we are refunding his money and no longer servicing his lawn.
