Whirlpool Water Dispenser, B10P, Missing Drip Pan

Hello. Whirlpool said my Model B10P, WHKMB10P, water cooler is a discontinued item and they cannot provide me with another white plastic water drip pan. I tried both Ebay and Amazon plus other websites, had no luck. Can anybody please help me in locating a company that has this part for me to buy? Many thanks everyone!
