Battery Dead Problems of Mercedes Benz CLA250

My son had to be cut out of the seat back because it was too tight and wrapped around him. The seatbelt strap was locked and would not extend out at all to loosen for extra length on the strap. The seatbelt strap was so tight my sons stomach was was cinched to the point where he couldn't breath. I'm not sure why the suspension on the strap was locked every other seatbelt had extended strap. This was a scary experience and could have severely hurt my son. This is unacceptable for the price I paid for this vehicle and not to mention my child's safety. I didn't take any pictures of the strap around my sons stomach because he was in pain and was frantically trying to get it loose and cut. I have pictures of where I had to cut the seatbelt. I also have a defect with my electrical which I causing my battery to die. The car will stay on completely without the key in the ignition or started. I have video of that as well. This is completely ridiculous for a luxury vehicle. My main concern is the safety of my passengers andy son simply unbuckling a seatbelt and getting strapped in because the suspension of the strap would not loosen and was locked is unacceptable. I tried everything to putting the car in drive pressing the brake to see it the strap would unlock and nothing worked. My son was in pain because of this defect o had to cut the seat belt strap off frantically. This is not okay!.
