Adult Tricycle with everything (Winter Haven Fl 33884)

I bought this bike before a big fall injury and now cannot ride it. It has never been use. I got Amazon service to assemble it but they did not do it correctly. They only refunded the cost. They put the chain cover bracket on incorrectly and the chain changer wire is not tense. So needs a bit of fixing. All tools and manual will help someone correct their errors.
