Long Life Fruit Juices need to be tested

At least on a weekly basis we purchase long life fruit juices, either they have been retained in the store for too long or they are not "long life". On occasion we have purchased Pure Joy - which lasts for approximately 2-3 days and is then sour. We now tried Pure Fresh, exactly the same issue. The latter was purchased on Friday, 3 June and on the juice BB date is 12 June 2022, not so, these juices are already off and the carton bloating. With the cost of living being so expensive one just cannot afford to keep replacing drinks that go off after the 1st 3 days, the question is - how long are they kept on the shelf and were they good to go originally? Tried calling the Customer Care Line and the call was promptly dropped. I would like either a refund or vouchers for the juices. Have pictures of the codes and the cartons. Will there be a response, let's wait and see.
