what are apple doing with the 100.000 song limit?

I have more than 100.000 songs in my Apple Music library. About 70 % is pouched from iTunes. 20% is uploaded from CDs or other media and the rest is songs downloaded from Apple Music. However, when trying to download now I get the message that I can't as have reached the 100.000 song limit. I thought that purchased songs an my own songs did not count and that the limit was for songs downloaded from Apple Music. Also when Genius has been updated I get multiple playlists, i.e thousands..... What are Apple doing about this? Nothing it seems as I have opened a case with them in March and still no result! Anybody else with the same problem and have you been getting any help. My solution is to delete the iCloud library and start from scratch as I have the files on harddisc, but I can't do this myself. Only Apple has control over the iCloud library......
