I booked to repair a nail extension. There was probably a misunderstanding with the nail technician who only put the semi-permament gel on my nail, without repairing the extension (even if I specifically booked for the service), resulting in one nail a way shorter than the others. I did not insist to repair it as probably we did not understand each other, but I did not really like the behavior honestly (and the semi-permanent gel on that nail after 3 days was already ruined).
