Cancel Duplicate Shipping Labels with different tracking numbers

[patrmed5501]

I created a shipping label. Before I printed it, I realize it was for a Priority Flat Envelope (should have been Ground Advantage) I went back, thinking this would cancel that label and created the Ground Advantage label. Wasn't until I attached the Ground Advantage label to the package that I realized I was charged twice. It also showed as a multiple shipping with 2 different tracking numbers. I was going to  cancel both labels but only canceled the  Ground Advantage. I have not been able to cancel the Priority label.How do I cancel both labels so I can basically start over? And will this cancellation take place immediately? I still need to ship my package. Please help!!!

You didn't need to void the Ground Advantage label as it was correct.

You can void a label within 5 days of purchase here:

It will take about 14-21 days for the refund to come through.
