Just like title says, I think it glitched? had to double pay for a label I didnt use and voided. Please help 
Hi, @Mermeladazul .
To clarify, Shopify Shipping labels can be voided up to 30 days from date of purchase. Only labels that havenât been used (ie. scanned by the shipping carrier) are able to be voided.
A voided label will also generate a shipping credit to your account, which will be automatically applied towards any shipping label purchase with any carrier through Shopify Shipping. If you navigate to Finances > Billing on your Shopify admin, do you see a shipping credit within the Credits area? If a shipping credit is still available to be used on your store, it will appear in this section of your admin.
If you donât see any shipping credits available on your end, our live support team can take a closer look at your account to troubleshoot the situation further. To get in touch with our live support team, youâll need to login to your store via our Help Center here. Once logged in, select a topic that best fits your query or situation. From there, youâll be taken to a page with a list of relevant support articles, and you can scroll to the bottom of that page to select your preferred contact method with our team. Our team can then assist you further and, if required, liaise with our shipping specialists to investigate your situation in more detail.
Apart from this issue, how are you getting on with your store?
Hi, I have a similar question and I canât figure out where to see my shipping credits. I voided two shipping labels and got credit for one but not the other. Iâd like to see whatâs going on with the credits before I reach out to the team. Under âbillingâ it just shows my bills, not even the credit I did get.
Thanks,
Rachel
Hi, Rachel! Any credits should appear in the current billing cycle section under Settings > Billing. If you donât see any credit information there, please contact our team via the Shopify Help Center so we can investigate. -Sophia
