I have only been on LS a few years. But it does not appear as though a lot of folks have much face to face interaction with their customers. I know with many of my accounts, its next to impossible (I even have 1 older lady who will scurry up the driveway and shut the garage door when she sees us coming). But from reading a lot of posts over these past few years, it appears many are hesitant to have a conversation with their customer.Situations like this can be resolved with a cordial conversation. I'm not sure what makes it so difficult. it is for me too. We just assume they know how bad they're messing you but really they probably have no idea.
I DO agree with you in that a simple conversation with them would, at the very least, give you some idea for why their yard is left the way it is.
For me, if the pay is on par with the time and work, I'd find a way. If it kept getting worse and worse, and I could not speak with them about it, I'd dump them.
I am a huge fan of face to face whenever possible.
