Dropped my Canon A2 and it has encountered a few problems

So I dropped my Canon A2 and it landed on its bottom. I see there is a bit if damage to the exterior by the command dial. The front cover popped up a little bit. I hear something in the body shake. When I switch modes it doesn’t work properly (ie: switched to manual mode and the shutter speed nor the aperture appears on the LCD, won’t turn off on L mode). When I press the shutter button it still functions. What is wrong with the camera and what can I do?
