Bad customer service

I ordered a laptop from them but didn't receive it, was told that it would take 2 months to receive my order, then was offered another one. Which I accepted because it had the same bundle. When I received the order it was only the laptop, nothing else. I was just told they are escalating the matter. Ok.... 2 days after receiving the laptop I decided to use it.. It has worked properly from day one. I asked them to come and collect it as it's not working. Again I was told they were escalating the matter. How do you escalate a matter for something that is brand new and not working. Just come and collect it. Replace it or refund me my money. There is no number to call and they don't respond to your whatsapp messages if they don't want to. Bad service!!!!! This is very frustrating
