We finally got our windows installed two weeks ago

First I want thank you all for your advices to select the right models, types and options
Our new windows look great and we already got several compliments from our neighbors who are now also looking for replacing their 25y old single pane alluminium windows
We were lucky that our previous windows didn't leak and no rotted studs were found
But some builder-grade wood sills were rotted so we decided to replace them all by acrylic models for a unified result.
The overall result looks great, but looking closer, I have some questions regarding the "finish"
To fit the new windows with thicker vinyl frames, the installers cut the drywall casing and result was not always sharp, straight and clean ending up with some irregular 1/4-3/8in gaps.
Once the windows were properly screwed, the installer went pretty generous on the caulking to hide those gaps even sometime overlaping some drywall damages that could have been patched first for a better finish.
After few days, some holes opened in the caulking since it leaked in the opening resulting in an improper sealing.
Also the acrylic sills they used are 1/2in thick while the old wood models were 3/4in, I asked them if it would be a problem and they told me not at all, but I was surprised that they didn't lift the new one up by 1/4in to compensate the thickness difference.
Also since they replaced the sill and they did the caulking the next day, I also noticed that they put no foam to fill in the space around the window inside the wall
Here are few windows to give you a better understanding of what I am speaking about
Honestly for $20k is it normal quality work for an installer awarded as the Elite Pro Select Contractor by Simonton itself?
ABC Supply missed one window in our order and they have to come to install it when it is delivered.
They said it would be in two weeks, but I don't believe it probably in 1-2months
Thanks God the majority of the caulking looks nice, but your opinion will help me to decide if I ask them to redo the sections of the caulking which look really bad
