Respected Sir,
This is with reference to Salesforce Trailhead Challenge .
On 2nd February 2015, I fulfilled challenge requirements.
On 3rd February 2015, I got an email to confirm Shipping Address.
I had already confirmed it.
Could you please update me the status for the same?
Mit freundlichen Grüßen /Thanking you and With Best Regards,
