Hello. Anytime you have questions about getting credits give the sywr department a call. In fact, I called them today about some credits that I didn't receive at Kmart while shopping today.
Follow the prompts to get to a rep and they will be glad to help you.
I've called them twice now and while the wait time was a little long, it was well worth it for the great response I received.
The number is 800-991-8708. Good luck!
