You’re very welcome ?!.
If the dents are small and close together and more importantly the paint finish is NOT broken.
Plus, he or she has easy access into the wheel arch, then also behind the plastic splash guard in the wheel arch, then it is pretty straight forward task for a good PDR person.
They will either use a glue pulling technic or ( and ) very likely roll out them dents from behind, pretty quickly.
It’s just a shame you end up paying for somebody else’s mistakes / carelessness

I know the feeling you get when you first discover the dents, it makes you feel sick.
Prices for the work will vary of course, it will depend on the time required and the level of work involved, plus your location in the country regarding prices.
But going by your description of what sounds like these very small supermarket dents, in my area I would be expecting to pay out around £100 - £130 ( ish ) ???.
Not too spiteful, but an expense you could do without on a new car.
Good luck and I hope you get it sorted
