1995 Buick Lesabre body & structure problems

While leaving an intersection I was traveling down a slight hill , I heard a strange sound and realized I had no steering the wheel was turning ,but with no control of the car . The car hit a telephone pole that was installed to hold up 4 mailboxes . The engine carriage of the car that is bolted to the frame separated from the frame past the bolts causing the steering connection to come apart , the car is totaled . Thank you gm/ buick engineers .
