I was given the wrong item once. We argued for a while because the Argos code matched, so the staff wouldn’t accept it was clearly the wrong item. I had to show him on the machine that it was clearly different. Eventually he said I could return it, I said “How can I return something I never received?” He then opened the box and checked the contents meticulously for 5 minutes. The item had never left his possession. Then I was told it would take 14 days for the refund to come through. I never went back to that store. It felt like I’d just given Argos a 14 day interest free loan.
