Hi Babyyak,
Thanks for the photos. That is definitely a warranty and it will get taken care of promptly. The email address you sent to is not correct. The best way is to use the form here:

Have you contacted the retailer that sold these to you? They will also likely be able to send you the part. If those two things don't get you a quick solution, we will be happy to send you the part.
