Send back the damaged part using a return label provided by Styku.
Step 1 : Open up the box with the replacement part that you received. There should be a return label inside.
Step 2 : Use that same box you got the replacement and put in the older part and attach the return label to the outside of the box.
Step 3 : Either Schedule a pickup with FedEx on their website, or drop off the package to a nearby FedEx location.
Step 4 : If you do not see a return label, visit www.styku.com/help and submit a ticket to request a new label.
