It's easy to misunderstand things here; I wouldn't take anything anyone has said the wrong way. Lots of us try to answer as many questions as possible and sometimes things seem more "curt" than they really are. I think, looking at my prior response, that I just misunderstood your specific situation.
I will offer one little bit of advice about Disney in general that definitely applies to DVC just the same as anywhere else: Always ask twice (or even thrice if necessary). There is often vastly different knowledge/skill/training/etc levels from one cast member to another. So the next time you don't get an answer you like, take a deep breath and just call again as if the first call never happened. I can't tell you how many times I've done that and had a completely different experience, to the point where I wonder if I even dialed the number correctly the first time.
Most recently DW and I had a non-expiring park hopper redeemed instead of our APs because the guest services person didn't order them correctly when we activated the APs. I noticed this when I got home since these issues are common, and called the ticketing department. The first agent tried to help -- even checked with a manager -- and apologized and said that had to be dealt with in person at guest services. I thanked him, left him a good survey (which is always good to do because it really does help them), called back 30 seconds later, and the next agent issued us one-day replacement park hoppers right there over the phone. I think that in your situation, had you called back, you would have had a similar experience
