That night I took timestamped photos of the empty doorstep, filmed the tracker screen and saved the order receipt, then uploaded everything in one clear packet. The packet was sent to instacart where a specialist verified timestamps, approved a priority remake and scheduled a courier redelivery within a few hours. The agent also confirmed a courtesy credit and emailed a summary of actions so nothing was left informal. Tip: attach dated evidence, request a specific remedy up front and ask for local escalation to speed real results.
