On the 6thI went to Dischem Centurion to buy the red plug voltage protector for my fridge. I'm partially blind so when I get to the store I explain to the staff when I need assistance in identifying whst I'm buying. Yesterday I asked staff member who was packing at the isle of the plug I was buying is the red one anomaly used for fridge to protect from high voltage. She looked at it and said yes. Today my gardener says I bought the one that says TV only. I've already threw away box since it's refuse day Tuesdays. Dischem is refusing to take item back because I thew box away
