Thomann Plek Service Nut

The service of replacing the nut with a GraphTech TUSQ was supposed to enhance the standard of my new guitar. When purchasing the guitar with the additional nut replacement service using the PLEK machine, I expected the work to be done with the highest precision and without any damage. Unfortunately, my expectations were not met.
On the fingerboard, near the first fret, there are clear scratches that could have been avoided with proper protection of the instrument during the process. This is especially disappointing, as the price of the service was considerable given the cost of the guitar, and moreover, it does not allow for a refund.
I believe the technicians should have taken proper care to protect the fingerboard in order to avoid such defects. Unfortunately, the final result does not meet the standards that should apply to services of this kind. It is a disappointing experience, as every time I pick up the guitar I am reminded of this flaw.

After helpful advice from a rep, decided to add the service. Was buying a B stock guitar as replacement for a return of same model. For 60 euros I received both a better B stock item and a well cut and seated nut, low string action and good intonation. Debated whether to buy a new or B stock, but I think accepting minor pain defects and a much better set up guitar vs the lottery of buying a new low price guitar, was a chance worth taking. Only a shame that Thomann don't offer a service in between this and the lowest cost plek machine service (200+ euros versus 60 euros)

One minor - is that the technicians left the old blackened b stock strings on the guitar. It would have added 5extra minutes to the process to put new strings on. The ones on the guitar are blackened, dead and need to be changed.
