I had a sale recently and the customer was charged 3 times.
They did not reach out yet to complain, and I am not sure what happened exactly - I don’t know if this is a bug in our code or if something went wrong on their end. When testing through the Billing API on test mode it was working correctly.
Hey @diego , thanks for reaching out. Since this is related to a specific merchant, the best spot to reach out would be through https://help.shopify.com/. You may need to ask the Help Centre AI to direct you to a person at first, but if you mention you need Developer Support assistance from a human specialist and share this thread, it should connect you to my team either via chat or by email and we’d be able to assist that way.
For issues where we handle potentially sensitive billing info we can only handle that through our Help Centre support paths.
Hope this helps, if you do run into any blockers, please let me know here and I can potentially look into things internally on our end to assist further.
