As you say, neither of these appear when searching on the title. I assume that they no longer appear at the itunes Store URL you were given when you got the acceptance email.
The feeds are difficult to read because there are very few line returns in them, but as far as I can see they are OK. FeedValidator comments that the 'link' tags are empty - this would mean there is no link to a website on the Store page, and I wouldn't have thought was a reason for removal - and that one of them has some HTML in an 'itunes:summary' tag - that's no advisable but certainly not fatal.
If a podcast is removed the author normally receives an email saying so (though not usually giving a reason) - reasons include technical issues with the feed (apparently not the case here), unacceptable content, or copyright infringement - which don't appear to be issues either.
So I'm afraid I can't offer an explanation. You could try contacting iTunes Support - they often aren't as helpful as one would like but possibly you might get somewhere with them.
Go to
http://www.apple.com/support/itunes/ - click on 'Other iTunes Store Features' in the list and then on 'Podcasts'. You will see a link to 'Express Lane', which will guide you eventually to some contact options.
