Is there any point reporting map errors?

Went along the A46 and A46/A45 Coventry ring road today and the speed limits were displayed incorrectly on my Tomtom:
Totom said I reported all of these back in January so was surprised they had not been corrected. I've just checked, and Tomtom have rejected one of my previous corrections and the rest have been ignored. As Tomtom have ignored / actively rejected these errors for many months on what is a major trunk road (A46/A45) it makes me wonder if there is any point reporting map errors? Over the last month I've seen lots of other errors in the maps, but I can't see any point in reporting them if they are not going to be actioned. Also makes me wonder how inaccurate the rest of the map is?
