consuming dangerous drink with things inside

I bought a pick n pay product the 100%boxed juice on Tues evening we were having a hard time pouring it so after drinking the juice halfway we decided to cut the box so to see what is inside but we got the shock of our life.We found this disgusting thing inside w don't know what it is it looks like a ****** a plastic with things inside.So we took the boxed juice to pick n pay Wednesday morning but we didn't't get the help we wanted at all.coz our main issue as to be taken to the doctors and get checked also this disgusting thing to be tested at the lab.but the managers told us that the superiors told them that we must pay ourselves and wait for procedure..and it takes 14 days but I can't wait for that long worse also my 7yr old son drank it also..today Thursday we went back again to hear the way foward but till today the boxed juice is still in their offices it was not taken to the lab they are only woried about their image what about the health of 3 of their customers.what if w all die now still waiting for procedure all they care is money only..I really need help so that w can go checked since w dnt knw what we drank what if it was a ****** with *****s imagine so disgusting
