Photographer Issues After Wedding

Hey ladies! I am desperate for advice. To make a very long story short, I’ve had problems with my wedding photographer from the very beginning. But I had already paid her so much money (the deposit) I put up with it. It has been 20 weeks since my wedding and I have still not received all of my bridals or wedding photos. My bridals were taken in August, I have 17 photos from that, and my wedding was in September, and I have 47 photos from that. Is this normal? In her contract it states an 8-16 week return. I have asked her multiple times (very nicely) when I could expect to receive the rest of them, and she either doesn’t respond or she says she will have them to me the next week, which never happens.
I am afraid of being rude to her, because or contract is technically not legal. When I first booked with her she sent me a blank contract and she would never give me the information to fill it out. I just let it go because I didn’t think there would be any problems. She showed up to the wedding on time and even stayed later than I paid for, but I am getting anxious about these pictures. I paid 1400 for them and I just don’t know what to do at this point. Any advice appreciated!!!
