Pick n Pay Hyper Ottery

I placed an online order on 15th March and canceled the order a few days after. I received an email from Pick n Pay saying they would contact me and will be actioned accordingly. I still have not received any call or refund from them! I called them and never got through I was on hold for more than 5 minutes and sent 2 emails thereafter!

I would like some communication from them, it would be appreciated
