Non delivery

I placed an order online for a product early in May. It has still not been delivered. I have phoned 3 times this week and each time they tell me the order is “Out on delivery”. I live in Johannesburg hardly out in a rural area yet it has taken 4 days of being “Out on delivery” to not be delivered. The tracking number the provide is a joke - if you try to track all it shows is the tracking number - absolutely no other information whatsoever. I want Edgars to cancel this order and refund me. I will never shop with them again either in store or online. They haven’t got a clue what they’re doing.
