Ukulele fret repair and ding repair

Hi everyone,

I am new here. Need some help.
Most luthier I looked up are builders of ukes..
Who can I sends my ukes for repair?
I have a new Kamaka that I found a vertical groove on the first and second frets, covered by the a string. Had it for a few months, rarely played. Discovered the grooves today when I was doing vibrato on the a string. It made clicking sound.
Also acquired a pre-fire Maui Music. Some old dings but I just added two new dings 1-2 mm each. Any skillful masters out there I can send the ukes?

Thank you.

If you are not satisfied with the ukulele, my advice would be to contact the manufacturer (Kamaka in this case) and see what they have to say. I'm sure they would be more than happy to address your problems.
