Horrible Service and Customer Feedback

I ordered something on Black Friday, since the price was good and I was in desperate need of a new phone case as mine is broken. A few days go by, and knowing I checked the lead time I can see they take up to 72 hours to process. Come 72 hours and I follow up for a tracking number. They said ‘sorry it will take 10 days before it gets shipped out even’ oh okay, that’s okay. I then ask for a refund. Since I know I need a new case and don’t mind buying one here around me. Just thought I’ve always wanted to order from Hey Casey so let me give it a shot. When I asked for the refund, very nicely might I add, they said they are unable to refund me since of their policy that they can’t refund on sale goods. This was not clearly stated on their website unless you click on two links to get there. Mind you I was shocked, but it’s fine. They said they would hurry it up, so I said Okay I will wait. Finally get my tracking number end of the week, and I’m impressed since they kept to their word. Monday I see delivery failed. I work in Logistics so I don’t mind phoning couriers. I called Dawn Wing and the lady said this parcel is on its way to Durban as there was no address on or address added to any waybill. No waybill? How does that work? I gave them my address. They said it would take three MORE days to come back to Cape Town. I message Hey Casey and they apologize and say they will follow up. I leave it for a few hours and message them again asking if they’ve had any feedback. They said they are still waiting. So I phone Dawn Wing and within 3 minutes I get feedback. Why was this so hard for them to do, since I ordered from them surely they should be the ones to do this if they forgot to put a waybill or address on?? I message them back saying I followed up so they don’t have to. They thank me. Why? Why are you thanking me for doing YOUR job? This is the first time ordering with you guys and I have NEVER in my life written a review, but I wanted someone else to see before they order. I don’t even have my phone case and I’m put off. If you just gave me a refund as I asked while I was still in a good mood, then you would have been able to avoid a review from me. I have to wait two MORE days before I get the actual package. So tell me, would you order from them to experience this? I don’t want to buy another phone case if I will have one in a couple of days BUT if I did, I could have had one TWO weeks ago.
