If the rental agreement does not say that the member must add the dining plan if requested, there's nothing that the company can do to help you.
The rental brokers have absolutely no access to the reservation, and cannot add anything to it, or make any changes. The member that made the reservation for you is the only person that DVC will allow to access the reservation. DVC Member Services does not make exceptions to this.
As to why the member won't do it, I can make a guess. When the member books the dining plan for you, they must pay for all of it at that time. That's hundreds of dollars, or more, that they're putting out, trusting that you'll pay them. When the dining plan is added at the time you make the room reservation, it's not a big deal, you're giving them the money right up front.
If your check-in date is getting close, the member may not want to take the chance that you won't pay. If I were the member, I'd be hesitant to do it unless I had the money in hand, or the renter's credit card number to use for payment, before I called Member Services and made the purchase. Some members get around this by doing a conference call with the renter and MS, and the renter gives MS their credit card number. Your member may not want to go to the trouble to arrange this. Yes, they can always cancel the dining plan if you don't pay, but if I remember correctly, the plan has to be cancelled a certain number of days before your arrival date. If it's getting close, the member may not feel that there's enough time to get your money before the cancellation deadline, and they may be afraid that they'll be left holding the bag.
And even if there are months to go before your trip, it really is the member's choice as to whether they want to do this or not.
Not that it would help you now, but for future rentals, it's really best to tell them at the time of the initial reservation that you want the dining plan. Even if you plan to add it later because you don't want to put the money out so far in advance of your trip, at least let the member know that you'll want to add it X number of months before your trip, so that payment concerns and any issues can be handled ahead of time.
