Can't get hold of Dog Box SA after paying them.

I ordered 3 large Henley beds last Saturday and paid via PayFast. I received an email confirmation from Dog Box of my order. Since then I have emailed them 3 x, posted on their FB page twice and sent them a Messenger request to find out when I can expect delivery. I have not had any reply or response back. I tried the WhatsApp number on their Website but it says the number in not on WhatApp and needs to be invited. There is no other phone number listed on their page or website. This is a lot of money for me and I have been saving for months to be able to afford new beds for my dogs. Now I think I'm never going to see the beds.
