Guess uncontactable.

I placed an online order on during lockdown, which I understood I'd only recieve my order once courier services resume. When courier services resumed I started tracking my order. Realising my order was shipped days ago, but I haven't received it yet, I tried to do telephonic & email follow up. The customer number is not answered no matter the time during the day & all the email addresses are either blocked or non-existant. These are addresses on their website as well as those communicated to me via the online purchase confirmation. Can some1 please call me to shed light please.
