Electrical Jack problems of the 2003 Cadillac Deville

Got a flat tire. Stopped on a paved street and put tire jack under front right undercarriage as indicated it should be placed. I raised the jack to remove the flat and then had to raise it more to install the temp spare tire. The jack collapsed on the temp spare and the body of the car hit the pavement. I'm fortunate I did not have a foot under the car or that I wasn't putting the temp spare on the wheel when it fell down. The jack has a grove the fit into the car undercarriage and it was installed correctly but the jack collapsed from the weight of the car as I raised the jack. I was about one inch from getting the temp spare on the wheel. I contacted Cadillac on chat, ref# 8-4056609660, and requested a free jack replacement. I was told my car was purchased without a jack as jacks were optional equipment and original owner did not purchase one. I find it hard to believe that a 2003 $30,000 plus vehicle was bought with no jack for the temp spare tire. I feel Cadillac owes me for a new jack and probably for the damage caused when the car fell and hit the pavement when the jack collapsed. What do you say? did 2003 not require tire jacks with new vehicle purchases? I would have been in real bad shape if the local mayor had not helped me get the car up and the temp spare on. Did I get the Cadillac chat bum brushoff? thanks for your help.

When using the jack to replace a blown tire, the jack collapsed and caused damage to the vehicle. The scissor jack hinge hooked over a pin and it came apart. The vehicle was not supported by the jack.
