On the contrary, moustache distortion, especially of this degree of
severity, is something that should cause you to run a mile. Unlike
pure rectilinear distortion, it is not something that is easily
corrected in post-processing.

The resolution and CA of the 18-55mm lens are both in the expected
range for a cheap kit lens. The distortion is not.
