X-press Mart Formerly was a Sinclair Expired Juice, called me a liar on phone.! Sugar Creek, Missouri

I had my boyfriend grab me my favorite juice drink this morning while we were at the gas station getting gas and cigarettes. So he grabs me a Fuze brand Tropical Punch. I get home and drink part of it. Then halfway through, I realize its expired on October 10, 2011. I call the gas station and tell the guy what happened, he checked the shelf and assured me it wasn't purchased there since the others said some date in 2014. I said no sir I was waiting in the car, I know it came from there.

He said well come check them. I said it doesn't matter, I know mine is expired by almost 2 months and plus my boyfriend has the car at work until night time. After he still says it didn't come from the store, I call the drink company to see if maybe its safe to drink. I'm a little worried because I am pregnant and dont want anything to hurt my child of course. She says no, its not safe, there are no preservatives so its not safe at all. Im very concerned and upset since I always go to that gas station. I will go tonight and see what happens. But I'm concerned for my babys health most of all.
