First; lets see if the dealer takes care of it or not. I would call back Harley CS if they don't; I had called them and they were pretty nice, so it could have been the person you spoke to.
As far as having your original seat re-worked; don't bother. I had that old style seat on my '09 and had MCC redo it. While they did the best they could and it was a lot better the new "low" seat was what I needed. Alan at MCC told me (an a lot of others as well) that he does the best he can do with the old style but they are just a poor design and there isn't much that can be done. Don't waste your money having the original altered, get a new low seat or go aftermarket. For a while Harley was selling the new "low" seat for about $150 list and dealers were discounting them to about $130
