Frustrated and unhappy

I ordered a hisense smart tv on 19/10/2020, the website shows that the order will be delivered in 2 business days. The contact number has been discontinued so the only way to contact them is via email. I sent an email on 23/10/2020 and the turn around time to get feedback is 48 business hours, today is the 28th and I haven't heard anything from them. The service is non existent. This is the most frustrating experience.
