I purchased a 5d and a 400mm 5.6L lense in November. Sent all the proper paperwork for the rebate on Dec 6th. It was received and signed for on Dec 11th. On the web site where you can check on the status, they still do not show it received and this concerns me. Should I be concerned or is this normal? I cannot find any phone # on this site to check. If you have any experience with the rebate system, would appreciate if you would let me know what you think about my situation.Thanks.
