I am a bit confused, I recieved the email from UPS which says

***Do not reply to this e-mail. UPS and the shipper will not receive your reply.

This notice alerts you the shipper requested a return shipment from . A UPS return label has been created and is in transit to the pickup location.


Message from the shipper:
To exchange your Kryptonite lock: Put your lock(s) and at least 1 working key into a box. Attach the UPS return tag and drop off at a UPS location.

What do I do now?
