Should I get Heliopan to replace my filter?
 

Sorry for starting a new thread (and cross-posting), but I panicked a bit when I saw the below picture

In the other threads about Heliopan cross-hatch vignetting, I noticed that some users got Heliopan to replace their filters, and the replacements are claimed to be free from this ugly effect - what is a consensus here? Should I complain about mine (only vignettes on wide lenses; the screengrab has been taken from the kit lens at its widest; the vignette starts to appear at two ticks from the "Close" end of the filter scale):
