I had a huge pain when I was trying to buy mine out. They accepted my offer, but then never sent me the paperwork. Call back, no record of the offer. Make the offer, accepted, "we'll call you in 48 hours", never heard back. Repeat about 4 times...Update - I called again - talked to another person - she had no problem accepting another offer from me (of course now I need to wait for 7 days for answer). Looks like a bit arbitrary and depends on the person handling the call.
