PIPS Landscape

I went outside after he left to look at the work done. I have a little less than an acre of property to mow. He missed big chunks of my land and even ran over some of my flower beds with his mower. I called him after I came back inside and told him I didn't want to micro-manage but I wasn't satisfied with the work done, especially if I paid $50 for the service. He told me he regretted to take on the job since it turned out to be bigger than he expected. He should have looked at this before he agreed to mow my lawn. He also complained about different things in my lawn being too steep in places or tree stumps, etc. He lives in the same neighborhood though and a lot of yards in the neighborhood are just like mine. He should have known it would be like this. I called to cancel the services, even though I had originally verbally agreed for the entire season. He told me he would have to get his money for the second mowing, but I told him I had already paid the $50 for the first two cuts that week. He told me that I have to pay $30 for the Thursday cut even though he told me specifically that it would be $50 for two cuts. He hung up on me after I told him that his services were already paid for.
