Schwinn Network 1.5 Womens Hybrid Bike 21-S

This bike was used a grand total of two times before the chain started outright slipping off every single time I pedalled a full rotation (I had spent over a month by that point just gradually buying safety equipment.) - The shifter had broken after the first use due to falling off a half-foot curb while shifting, and the only clue I go that anything was wrong before attempting to shift with the left shifer was a small clicking noise while pedalling.The second ride, I tried to shift and didn't. Then the clunking started as I was heading back home at 8 PM.Then, at 9 PM, on a friday night, during sub-30-degree weather, the chain slipped totally off. I put it back on and tried to get far enough to safely check what was wrong... and after one full cycle of the pedals, it fell off again. I put it back and the same thing happens a third time.I spent several hours stranded. Hypothermia was setting in and my friends had been unable to locate me for almost an hour and half after that. My fingers kept losing sensation when I wasn't holding them against my chest under my jacket. I was starting to feel warm, and giddy. I knew I could die, and for some reason it became hillarious to me. I don't understand how, and it's not funny now.My friend lucked out and found me at the side of the road. I was too tired, I could barely must the energy to move. Every step I took was careful, measured. I was leaning on my bike for balance. Then we had to take it apart and I had to climb into the car. I managed to get in, but I had to move slowly to make sure I didn't step in the wrong spot.Today is two days later. I checked and I'm missing several of the 6-8 tiny parts that had to be removed to fit the bike inside their car. Probably still in that parking lot. I spent over $500 on this bike, now it's nothing but spare parts to sell to recoup a fraction of the cost. I left my house for the first time in over a week then, but now I have yet another reason to stay home and avoid the outdoors, avoid having to risk freezing once more for the sake of a social life.I have learned to fear the cold, to stay home, and to never trust a bicycle again. This lesson was taught to me by Schwinn.Edit: if your box arrived damaged and you threw it out, you are stuck with the item. A replacement box to ship costs a minimum $169 and Amazon will not provide one or schedule any pickup without one. I am out a bike, a possible job, and the money I spent on this item.Schwinn cost me more than I spent on the bike. I am ruined. Never trust the returns department and never trust this brand.
