Front Seat Belt Anchorage problems of the 2002 Chevrolet Malibu

I purchased a new 2002 chevy Malibu on August 1, 2002. Four days and 250 miles later the front passenger window "exploded" while I was traveling alone down I-90 at 75 miles an hour. I feel there was a defect in the window or the car itself to have this happen for "no apparent " reason. I had to have the car window replacd and the right exterior of the car repainted from the flying glass nicking and gouging the outside of the car. I had broken glass in both the front and back seats. The window and painting was repaired under warranty through the dealership. When I picked the car up from getting it repaired I noticed they (bodyshop) had snapped both rear seatbelts. When I got the car home, I unsnapped the seat belts and noticed they would not retracted back in, but instead, just hung down onto the seat. I called cory peterson, head of sales, and told him about the seatbelts, and he told me to take the car in the next day, September 14th, to have them checked. My husband and I took it in, and dave halland looked at both seat belts and said, "they are worn out. " I said "worn out! the car is a month old!" he did not have replacement parts that that time and said he would order them and set us up for an September 20th appointment. I took it back on that date, and was told the parts were not in. He had another man check out the seat belts at this time and he said the "retractors" were defective and the entire seat belts had to be replaced. Dave halland again told me he would have the parts over night expressed and would call me when they were in. I waited and waited and finally called for dave on September 30th and October 1, 2002. And left a message for a call back. After no word, I called a requested to talk to the service manager. I was turned over to terry, and he told me the parts had been there for over a week. I told him I wanted the parts when they were removed and he told me I could not have them. I said, "I bought this car, didn't I?" he said".
