Caremark not shipping insulin with cold packs

I am furious! My daughter's insulin was shipped (via US postal regular mail) from Miramar Florida to Virginia on May 22nd and delivered May 29th without a cold pack to simulate refrigeration. My daughter has had diabetes for 11 years, and every insulin shipment she has received has been shipped with a cold pack. The manufacturers label says: REFRIGERATE. I contacted Lilly, the manufacturer, and they said they have received many complaints about this, and it is against their recommendation and the FDA's recommendation to ship insulin without refrigeration. I contacted Caremark and was basically read this policy by the pharmacist (also posted on their website) "Please do not be concerned if your order no longer includes a cold gel pack. Before we ship extreme temperature-sensitive medications, our improved system will check the forecast temperature of the city where the medication will be delivered. • If it's going to be under 32° Fahrenheit or over 85° Fahrenheit, we will ship using a method that requires signature upon delivery. Once the order is shipped, the plan participant will receive a phone call from us to let them know it is on the way. • If the temperature is between 32° Fahrenheit and 85° Fahrenheit, we will ship using regular delivery. • If no one is there to sign for the medication, the carrier will leave a note with instructions, telling the plan participant to either schedule another delivery day or pick it up directly from the carrier. How can they get away with this? REFRIGERATE means REFRIGERATE. How many hot trucks , planes, etc, did this insulin sit in and go to unknown temperatures?I f my daughter's insulin is not working properly to keep her blood glucose down because it was supposed to be refrigerated and it wasn't, and she suffers damage to her organs, or has DKA, or God forbid dies, that is a huge medical liability. How do you go about filing a class action lawsuit? I would love to hear from others who have experienced this, and who are interested in having Caremark stop their practice of shipping insulin without cold packs.
