Mr Price Online Failed To Deliver

I have just had the worst experience with Mr Price online. I ordered some items on 2/12/2019. And my confirmation email stated that the items will be delivered by no later than 11/12/2019. So on 12/12/2019, I called the contact centre and was advised that it is on it's way to the store. My husband also went in to the store to enquire. But there was no delivery. I called through again yesterday, 17/12/2019 and was told that the item was delivered to the store but the store has not checked it in yet, but I can still go to the store to collect. So I went after work and was told that there is no parcel for me there. the manager then attempted to call the contact centre and courier department. I waited in the store for close to 30 minutes while she was placed on hold and transferred from one department to another. I then left as I could not wait any longer. I called her today and she was told that the courier company will contact me today. I the called the contact centre once again, and was then told that the package was delivered on 11/12/2019 but because it was damaged and not in a good condition, the store controller sent the package back. No one at the courier company bothered to let Mr Price know that the package is sitting with them. Now Mr Price tells me that I have to wait another 5 to 7 working days to get my money back as they no longer have some of the items I ordered in stock. I was given the option of receiving a voucher but I do not want to shop at Mr Price online or in store ever again. Mr Price has no proper system for tracking orders. The app has an option to track but it always came up with an error message when I tried. Long story short, I want my money back ASAP!
