Working late and living on tight margins made that missing rebate suddenly important. I uploaded the receipt, transaction ID and a short clip of the app confirmation to the support form, explained the timeline clearly, then followed the case reference for updates. When the merchant stalled, I tried upside as an escalation route; their agent validated the claim, flagged a processing error with the vendor and arranged a manual credit. Progress messages arrived by email each day so I didn’t have to chase. The credit posted within the promised window and the whole exchange stayed tidy and documented useful if you need a quick, accountable resolution without phone marathons.
