It happens, but going crazy on here will get you no where. If its that upsetting report it it to your transportation manager. They can look who dropped it, but doesnt necessarily mean they will do anything about it. Ive had it happen to me but it was 2 bad ties. One flat and hanging off rim and the one next to it bald. Took to the shop and mechanic said no way they pre tripped or post tripped that trailer. I said i know but yet here we are can you fix it sir. He did but with a little cussing not at me but upset at people passing the buck. I did not report it or anything. Crap happens and sometimes we step in it.
