Sharon,
I'm a Disney CastMember, so feel confident that the advice I'm giving you is very accurate.
First, when you called to book the pontoon boat did you ask (or did they offer) the "Breathless?" The Breathless is a smaller boat that is a recreation of a 1940s runabout (sort of like a vintage powerboat). It's MUCH COOLER than the pontoon boats and seats six people. It's home marina is the Yacht Club, so maybe you'll have better luck calling the Yacht Club Marina directly. To reach anywhere at Disney, simply call the main Disney Operator at 407-824-2222 and ask to be connected to the YC Marina.
Secondly, your Event Manager may be able to pull some strings. (I know this for a fact!) Call him or her directly, explain the situation, and see if they call the Yacht Club to "work the system" so to speak.
Another great option (and a major WOW) is renting the Grand I Yacht at the Grand Floridian to see the Wishes fireworks at Magic Kingdom. You'll spend alot more $$$ on this option (I think the yacht rents for about $350 an hour), but it's worth it. Plus, since the yacht is much more expensive than a pontoon, the availability is typically much better. The yacht is large enough for groups up to 16 people.
And finally, people always cancel fireworks pontoon boats at the last minute. So, worst case scenario, keep on trying right up until within a day or two of your arrival.
Hope this helps. GOOD LUCK!
