Talking-About Wrinkle Free Face Creams

I busted my oil pan on a pot hole 2 months ago. The car sat in a parking lot for over an hour leaking massive amounts of oil out of the pan. it was towed to the dealership and repaired. they put oil in my car and replaced all the fluids. one month later my car began to act up and the oil light came on... there was NO OIL at all in my pan. i had to put four quarts into my oil pan. Now, another month down the road i am having to do this again. I really don't think it is appropriate. I had the car checked out when it ran out of oil th first time and they checked it and checked it again for leaks and found none. is it normal to replenish oil twice in a 2 month period in a volkswagen beetle?
