I picked up a customer a couple weeks ago. I went out the day they called to give them an estimate and got a call from them later that day that they would like me to do the lawn. I started out doing a quick clean-up and dethatching (very minimal work with not many leaves). I get done and the lady says that everything looks good. I tell her that weekly mowing will start around May 1st and get going to my other accounts that day. So at about 5:00pm that evening (7 hours after I had left) I get a call that they were unhappy with the job. I drive back over to their place from across town to see what the problem is. They first tell me that I didn't dethatch their lawn like I said I would. I told them when I gave them the quote that I would be using a tine rake dethatcher on my mower. But after explaining that to them another several times they still didn't understand that I dethatched. Then the lady starts tell me how I didn't blow the beds because leaves had blown back in to them. On top of all that, she starts to tell me that I didn't empty the bags on the mower often enough. After explaining to them another two times what type of dethatching I did (using the tine rake and not a power rake) they still didn't understand. I was trying to be very professional with them while I was there. I said to them that I was glad they told me they were unhappy so I could help correct the problem. Then they proceed to tell me that they weren't unhappy. I was finally able to leave and return to the other clean-up I was about to start. I returned to their place yesterday to clean-up the leaves that blew back into the beds. When I was finished the lady starts telling me how I need to take dethatching off my list of services because I don't do that. She said it was mis-leading because I didn't dethatch (which I did, I just couldn't make her understand). So far this lady has been nothing but problems and I can only see more to come as weekly mowing starts in another week. I am undecided as to what to do. I am debating whether or not I should just drop them or keep them. I didn't quote them high enough to continue to make return trips to their house. So now that I have vented a little, I need some advise as to what to do.
