On checking using our tools, it saddens me to let you know that your Amazon.com account under this current email address is not among those targeted customers accounts for this promotion. This is the reason for the promotion not being honored and you not receiving the credit.
Unfortunately this promotion is designed in such a way that our system targets few customers account dynamically, sends those customers an email regarding the promotion and honors the promotion on those accounts only.
