Sorry to hear this but this is entirely up to S.A and I don't think it's possible, you can try to submit your request from the support page. The time frame for remix-comp has to be rather strict otherwise it would be a never ending story.
Reminders were also sent via S.A social medias hubs in order to warn people and to do a "last call" announcement.
Time zone could be very tricky, therefore it's a good habit to set your submission limit date 24h ahead from what's announced on the web site when deciding to get involved IMO.
Beside this, it is absolutely not permitted to upload your remix on any medias outside the Remix Competition frame as mentioned in the rules :
- 8-Submissions may not be released or distributed for any purposes or through any media whatsoever except by label in its sole discretion.
For that reason, you have to take down your track from SoundCloud and I have to delete your second post with the sndCld link.
Sorry for the disagreement & the frustration and again feel free to reach S.A from the support page to try to push your request further but the SndCld link woould do no good here.
