It may well be, but that doesn't get anyone any closer to it being fixed.
Scope Repair Shops are not exactly thick on the ground to start with, and the one I can think of, Korth, likely wouldn't look at that scope, let alone be able to fix it, for what it would cost to just buy a replacement.
If it were a couple thousand dollars worth of Long Range Target optics, might be worth considering.
Or under warranty, which I kinda doubt, but if you want a hobby, chasing down and contacting the warranty provider and asking, might be a consideration. But the Warranty Center, like as not, would send out a replacement if they had one (or in fact, still existed) rather than actually fixing them.
My edjumacated guess, having played with a couple beat up scopes and even fixed one or two of them, is that if one direction adjusts and the other doesn't, the adjuster screw thread is stripped or there is a broken part somewhere in the mix.
If the erector spring, the spring which counters the pressure of the screws to allow the adjustment, has broken, or fallen out of place, both adjusters would be done.
In absolute value, that scope is worth less than it would cost to mail it any where. Thus, my recommendation to poke around and see, and shop for a cheap scope to replace it.
