Can you post a screenshot from usps.com showing the full tracking history for both packages? In addition, can you explain more about which US Customs & Border Protection Declaration form(s) you completed and describe in explicit detail how you marked those forms? Seeing the usps.com tracking history will confirm if the packages did or did not the clear the ISC Los Angeles facility. Once you post this information I can recommend next steps. You must also keep in mind that USPS codes are sometimes inaccurate and they may not match the actual status of the package.
