Inquiry Regarding Missing $5 Monthly Credit for GitHub Users

Dear Claw Cloud Run Support Team,
I am writing to inquire about the promotional offer that grants a $5 monthly credit to users who sign up with a GitHub account older than 180 days.
My GitHub account, [My GitHub Username：wangzi7654321], was created on November 9, 2020, which is well past the 180-day requirement for eligibility. I have successfully registered for a Claw Cloud Run account using this GitHub account.
However, after checking my account dashboard and billing section, I have not received the promised $5 credit.
Could you please look into my account and apply the promotional credit? Please let me know if there are any further steps I need to take.
My Claw Cloud Run account is associated with this email: [[email protected]].
Thank you for your assistance.
Best regards,
wangzi
