No delivery of online order

On 6 May 2020 I placed an order online, which they said would take 3 weeks to be delivered due to the Covid-19 lockdown.........it is now almost 7 weeks later and I still haven't received this order. I keep receiving updates on my order status, but none of the updates say when I would receive the order. Keep in mind that I've ordered baby clothing - chances are that the clothes I've ordered wouldn't fit the baby when I eventually receive the order. I have also paid the first installment for this order on my account.

I have sent a request to cancel the order via their online "enquiries" option, but haven't received any response from Edgars. I can't seem to find a number to contact their Online Orders department telephonically. I would like to speak to someone to cancel my order and credit my account accordingly.
