The most horrible Online store I have ever experienced

I purchased a few items online, on the 26 October 2024. I was told that it will take 5 to 7 working days for the items to be delivered. Today is the 15th November 2024, I have not received my full order. When I placed the order I gave them my correct delivery address, but for some reason they changed the delivery address, and when the 1st batch came, it came with the wrong delivery address, I have to give the driver directions to the correct address. I have been calling the online everyday to find out about the rest of the items I have not received and every day I get a new story. I ended up asking them to cancel the order and give me a refund, and now that is the problem. They are telling me that I should wait untill they receive the stock back from the courier and then they will process my refund. In all of this, none of the consultants I ever spoke to, came back with feedback, nether did I get any apology for the delay. I am expected to just understand that they have a delay. Today one of the consultants by the name of Prince, went as far as telling me that I am not the only one struggling with the delivery, I guess I am supposed to understand because I am not the only one. So I am waiting untill they receive the items back from the courier, then they will attend to my quiry. If they don't get the items back from the courier, then it means I an not going to get the refund. In the meantime, I must just wait regardless of when I wanted to use this items. I can't even go and buy them at another branch because I must wait for them to get the goods from the courier, then they can give me a refund.
