The steps to my mental breakdown

Our house was flipped before we moved into it. On appearances only it looks cute but it has been proven to us more than once that a lot of things were put together with gum and Elmer's Glue. One of those things was our front steps. The flippers put terracotta colored ceramic tiles on them - not a great plan for outdoor, high-traffic stairs. After about 2 years of weather changes the tiles started breaking and we had to have them re-done. Re-done included pouring, stamping and staining concrete.

We used this one particular company who at this time will remain nameless but trust me I'm very close to naming them. They were recommended by a friend and they did a decent job - when they showed up. They would do one thing and then take like a 3 - 5 week hiatus before they started the next part of the project.

Here we are now.
1 year and 5 months since they gave us an estimate.
1 year and 3 months since they started the project.
11 months since I have seen them.

The problem with that is that the steps are NOT finished yet.

I've tried quite a few things to get this company to come finish my steps but my new tactic is calling them every single day. Of course the phone always goes to voicemail when I call. I only have one guy's cell phone number so he is the lucky one who gets to hear my voice daily. I started out snooty letting him know of my frustration but since I get bored easily I have now changed it up a bit. Each day I have a new personality. Thus far I have used anger, humor, and calmness.

Here are some other tactics I am working on:
Threats
Spanish (just for fun)
Tears
Psycho Screaming
Silence
Lawyer Speak
Speaking each word backwards (I have a weird ability to do this)
Calling every minute for 3 hours

Still working on some others. I'm sadly having a good time with this and I might even be disappointed when (if) they actually finish our steps - what am I going to do with my time?
