Why do men not listen to women??

A little history behind this post. When my family moved to MS in November we found a house to rent. Its in a nice neighborhood and close to everything including my husband's job. The only problem is that the previous tenants kinda trashed the place. Now I realize that not everyone is a neat freak like me (my husband calls me the cleaning natzi), but these people were disgusting! No one should live like this!! I have had to literally SCRUB everything in this house from top to bottom. One of the things that was broken and had to be replaced when we moved in was the toilet in the master bath. The landlord sent a man out here to install a new toilet. Yay!! A week or so after installation I noticed that there was water pooled around the toilet. I got to looking and the toilet was leaking around the tank in 4 places. I called the landlord again, and he sent out the same man to fix it. So now that you know the history...I told the man when he got here where it was leaking. Now I had turned the water off to the toilet and drained the tank to stop the leaks. I told the man that I thought there was a crack in the tank itself. He said no, it was the bolts need to be tightened. I'm thinking why didn't you do that when you installed it, but I didn't say anything and let them do their thing. They tightened the bolts and turned the water back on. They said it was fixed and left. I immediately went in to check, and it was still leaking where I had said there was a crack. I called the landlord who immediately sent the guys back out. Now I can clearly see the crack in the tank, and I can see the water dripping from the crack. I show it to the guy when he gets here. You can feel the crack!! He still says its not a crack! They currently have the toilet taken apart and completely off the hole while they have gone to get a part. Why are they not listening to me??? They could have replaced the toilet and been done and out of my house already if they would just listen to me!! So frustrating!!
