License Plate Shortage

Long story short, bought a car in nov. Plates still haven't come. Temp is expired and got pulled over yesterday for it. Officer says he has not heard of any plate shortage and says if I get pulled over again with that temp I get a ticket. I have reached out to the dealership SEVERAL times for a new temp and again today after getting pulled over. They are refusing to give me another temp plate. What do I do? Will th3 dmv give me one??
