My medication was shipped FedEx overnight. But is was shipped on Friday, from FL to NJ, and with Deliver Weekday-Residential Delivery. I should receive it today, but I'm concerned that it's been subjected to high temps for several days. Who do I contact for a replacement if it arrives with melted cooling packs, and it's not cold?

UPDATE: I received my shipment today. It was in transit for 96 hours, from the time is was shipped until I received it. Ice Packs last for between 24 and 36 hours. Mine arrived totally melted, and not cool to the touch. Everything was warm. I don't know the temps it was exposed to during transit, I'm concerned about the efficacy, at this point.
