No shipping tracking details or proper communication since purchasing on their online store.

I cash purchased a laptop on the 30th around 12PM and opted for next day delivery. Until now, I haven't received any courier details. The delivery information on the website shows that if I place my order before 02 PM, I get next day delivery. But if placed after then, it'll take 2-3 days. I am gravely upset about the fact that I have no information to track my order. And was expecting it to arrive the next day as reflected on the delivery details. I've contacted the call centre, communicated via whatsapp, and logged a formal complaint via email this far. They keep telling me vague information about my "order is in process to be handed over to the couriers". It's been 3 days now, and I still don't have my order or any tracking information. Their services are extremely poor. This results in me logging another complaint. Not that it helps. I am continously been told that I will receive communication shortly. I don't know how long their definition of shortly is. I reached out again via WhatsApp and I am now completely being ignored. I need an ETA, tracking information or at least clear communication. I DO NOT RECOMMEND THE ONLINE PLATFORMS TO ANYONE. At this point I think the online platforms are ****. I'll try to get a refund, if possible. My advice - Try your luck in stores, maybe that'll work quicker or have better service.
