How can I delete my iMatch account and revert my iTunes back the way it was?

Question

I am having many issues with iMatch and want to delete my account and remove all of my music from the cloud.
Here are the issues:
1. My playlists are filled with "error" songs that cause playback to skip multiple numbers at a time.
2. When I sign off of iMatch and try and repopulate my playlists with songs imported from CD's I recieve a message that says " iCloud playlists can only contain songs from your icloud library.
     * This error message occurs even when I am signed-out of iMatch.
3. There are many songs completley missing from playlists, and none of my playlists were Smart.
4. When I try and restore my playlists I get the same error messgae over and over.
5. If I turn iMatch back on, all of the numbers get classified as "error" and the whole thing starts again.
I have over 25,000 songs and this is a gigantic mess.
Can someone please tell me how to compeltley remove all of my music from the icloud while leaving it on my computer? This includes all playlists?
Can someone please tell me how to delete/remove the connection with my itunes account and the icloud?
I am not asking for a refund, just a return to the way things were before I foolishly bought iMatch.
Thanks
David

Michael,
Thanks for your tip and response. I tried everything. I spoke with support for about 50 minutes the same day I posted. They informed me that even though I might have iMatch switched off, all of my playlists on my iMac have been designated as iCloud playlists. This is why I was getting the iCloud error message everytime I changed a previously iCloud-ed playlist. If I turn iMatch back on, these error codes go away because the playlist is automatically re-synced with the duplicate lists in the iCloud.
The support team suggested deleting my entire library from the cloud but did not have a procedure in place for this. Individual song deletions are listed in an Apple support document, but this procedure will delete the song from your hard disk as well.
So I went to work, re-organized all my playlists with iMatch off and received 100's of error codes in the processes. I found upwards of 200 (out of 25,000) songs that had been corrupted by the iMatch process and were now non-playable MPEG's. I have no clue how this happed becasue on my devices they are AAC files.
Long story short: Apple Service sent me a very apologetic letter, deleted my entire iCloud library and refunded all of my money.
The iMatch expereince for me was a complete disaster however, I must commend Apple for their prompt response and service.
