Once the package leaves Target's hands, it becomes UPS's responsibility. As a result, they are the ones who handle the reimbursement in the event that a package is damaged or goes missing. Regardless of UPS's findings, Target will not be issuing a refund or replacing the item. It will be UPS. So tell me why should I not be in contact with UPS? Their website literally has a page for customers to check on claims statuses and suggests calling them if you have questions about it.
All I needed to know right now is if the investigation had been completed, and thanks to their online portal I now know that it is complete. The next step is to contact Target again as UPS only issues the results of their findings to the shipper.
"File a chargeback and move on" is not valid advice. Chargeback is a last resort option after all other efforts fail to produce a resolution. In fact, some banks will not issue a chargeback unless enough time has passed to ensure that other attempts at resolution have been made. The original delivery date has passed and Target's estimate for a resolution (three business days) has also passed.
Depending on what Target says, then
yes a chargeback will be the next step. But right now I am doing my part and making an effort to resolve the issue with the parties involved. Attempting to charge it back now makes no sense when Target and UPS are actively working to fix the problem.
