Kala U-Bass Spalted Maple 4 NT

The guitar I received came with damaged strings (with very fine scratch marks, like they were dragged on pavement), some frets (12th on A string the most, but not only) do not produce sound at all, it's being damped down immidiately, and I don't know if it's fret issue, or saddle, or just bad guitar design, but it's hard to care at this point. I did try to higher the strings action, it did not change anything. I am really dissapointed, I tested harley benton earlier, but I had some concerns so I actually went for something I considered higher standard. But it's not, oh not even by an inch. I know it's probably cheapest models, my expectations were not high, but playability and new strings is kind of a baseline I think.
