How long for major street name issue to be corrected in Apple Maps

I was trying out Apple Maps again and like the progress that has been made, but there is an issue with the street name of one of the major streets here in Houston. I reported the issue a couple of times over the weeks, but it still has not been corrected. The problem exists on the iPhone (iOS 8.4, 9.02) and the Mac's Maps application. Some recent articles were saying Apple was making map corrections in the span of days or a week.

For some reason Apple has incorrectly changed the street "Westheimer Rd" to "Waterall Dr", and the real "Waterwall Dr" (a small road by the Waterwall landmark) was incorrectly changed to "West Dr". The interesting part is the incorrect name of "Waterwall Dr" is only between the Beltway 8 and 610 West Loop. The rest of the road still has the correct name of "Westherimer Rd". What's worse is the businesses along that 8 mile or so stretch of road now have the wrong addresses - they are listed as being on "Waterwall Dr" instead of "Westheimer Rd". There is even an Apple Store on that stretch (interestingly it is still listed as being on Westheimer Rd).

I really like the look and feel (and multiple route options) that Apple Maps has. I hope they are able to fix this issue soon for the sake of visitors to the city since this is a major visitor area and where the Houston Galleria is located.
