They take your money and don't deliver your products

Good day

I bought a lounge set from House&Home on their mobile app as this was only available online. This was on the 27th of September 2021. While I was paying, the website went down. Still the money went from my credit card straight into their bank account and the next morning I got a e-mail where they confirmed that they received the money and they will confirm when delivery will take place. An hour later they asked for my prove of payment because they have not received it. I had to confirm and send through and then they will give it to the finance department to see if the funds are there. This is now a week later and they sit with my R14,300. I do send the POP through daily and they just don't respond. Never, and I tell you never, have I came across a company with this ****ty service and replies to problems. Especially after a lady in the online department called Noni said she will call me back. This was last week Tuesday. Nothing is happening. They have got my money and I don't have anything
