Expired Juice

On Friday the 26 i bought ×2 Duo Tropical juices at Loftus Checkers store.Me and my colleques drank the juices and realised later that the juice has expired on the 21st of Jan.I had to return them.I completed the complaints form and no manager has got back to me. The service is very bad.The manager has no interest as even on the day when i returned them,he did not bother to check the other stock , untill my colleague took a video of the rest of the stock that was still in shelf and also expired.
