Y limit switch not working

hi there, i’m new here and hoping i can get some help, since i been trying to reach creality service but they seem to not understand my explanations and keep trying to send me a piece i already explained it doesnt work

as the video shows, the bed never stops moving backward once i turn it on out of the box, i literally assembled it, turned it on and this happens (btw this is also my first print ever)
i tried testing the switch, and wire going from it to the motherboard with a multimeter, and i can see continuity on both (but i’m still not sure if the wire is the problem since it was extremely bent on almost a 90 degree angle in some parts)

anyone have any idea what can i try to fix this? i’m really trying to avoid returning it since for some health issues i cant move too much too easily and carrying this thing gonna be pretty hard
