leaking tops on everfresh carton milk boxes

I am writing this email after alot of consideration, but have come to the realisation that if i dont complain this will make me loose even more money. I have bought a total of 8 six packs milk the past two months and each and every cap is leaking and the milk spoils within a day or two because the box is not properly sealed. A sixpack milk is alot of money and every single box i open is leaking at the cap and hot air (CT weather ranging anything from 20 - 45 degrees celcius every day) is most definately entering the carton hence the reason for the milk spoiling so quickly. This being an "everfresh milk" i can honestly say i've had nothing but issues these past two months. This is very frustrating and i am loosing alot of money. Could you please look into the matter as i am sure im not the only consumer experiencing this. I have sent an email but havent had any response to date.
