Delivery of order-NO FEEDBACK

I place an order 27 November20, Order 42414, with delivery date 10 December20. I saw that my order status has been stuck on processing since then. I have sent emails, whatsapps, phoned (been on hold each time, and then put through to an automated message that says caller is not available), left voice messages, and have received no feedback. Never in my life have I experienced such shocking service. All I want to know is when I can expect delivery of my fridge. In good faith I placed the order, made immediate payment, and all that I expect is that their side of the transaction be completed.
