ᐅ Poor Installation of Wooden Treads on Concrete Staircase in New Construction

Hello house building forum community,

I need your help and advice on how to proceed. Here is the current situation:
We had oak treads, oiled, installed on a straight concrete staircase in our new build, along with corresponding risers, by a supposed professional. The treads were fixed using two-component foam adhesive, but the concrete was not primed or pretreated in any way beforehand. The installer attached the treads using just the foam.
After about one month, 75% of the treads had become loose. The installer said this can happen, but he couldn’t guarantee that the treads would hold if reattached with foam. In his opinion, the treads only hold securely if screwed in. My wife was then convinced, and the installer fastened each tread with two screws. The drilled holes in the treads were covered with plugs, although almost every plug is clearly visible due to the wood grain. Well, I thought, I’ll have to live with that as long as the tread holds.
After about two months, a few treads became loose again despite the screws. The installer agreed to tighten any loose treads as needed. Based on this, I had another installer inspect the installation. He found that the treads were poorly mounted from the start, with too little foam, and that screwing treads in this way is actually outdated nowadays.
Now, the installer is offering to refund about 10% of the price and to have the treads refitted by another professional.
Should I accept this offer?
The treads were incorrectly installed twice, and my wife and I were poorly advised. This seems insufficient to me.

I would really appreciate any advice you can give me.

Best regards,
bierbaron

... one should get advice from a professional beforehand... Wooden steps are connected with tapered hardwood strips, which are attached to the concrete steps beforehand using heavy-duty anchors...

I assumed that he was a professional. This is an official one- or two-person company with a showroom and sales area. So you would expect that he knows what he is doing. Otherwise, I could have done it myself right away.
