Contaminated apple juice

A few weeks ago I purchased a 2 lire Combibloc pack of Apple juice,on getting it home it had blown up,and was clearly contaminated. My wfe sent all the details to RFG,as shown on the pack. After no resonse a few days later, the pack was disposed of, as it was in clear danger of exploding.To date there has been no response from the company. I guess it wasn't important.
