Bad Service

I purchased a Acer i5 laptop online on the 4th April due to having to work from home during Covid19. I was told because its a non essential item I must get an affidavit at SAPS and complete a form which I did. Still no delivery. When I called now I was told No Stock! Then was told it's a non essential item. What is going on I have already received my statement with 1st installment due yet I don't even have the Laptop!
