Worst customer service

This is the worst experience I ever had. I bought R2000 worth of clothing for delivery to my home. After registering and putting in my home address, etc and paying for the clothing - I saw that the delivery address was NOT the address that I put in. It was a store's address in a very ***** area where there is druggies in street that will stab and rob you. When I phoned this morning to enquire why this mistake appear on the app, I was told the delivery address on the system on their side showed my home address (which is 100%), but I was asked to take a screenshot of what the app is showing and I had to email it to customer care. Then when I phone to confirm why the store's address was still showing on the app, they told me it shows the delivery adress as the store now - which is not what I asked. They just changed the address to the ***** place and 10 emails and 5 phone calls later, I am still sitting with the ***** address on the app and my anxiety levels is through the roof. I just want the goods to be delivered to my home please. That is not too much to ask. The App is faulty - fix it. That is the whole reason of the screenshot. Then you ask me my adress, invoice and order nr and I gave it again.
