Delay after delay ... non-existent customer service!!

I placed an order for 6 items on 6 January 2021 and was told that the latest expected delivery date would be 28 January. I then received an email on 22 January to say that there was a delay receiving 2 of the items from their supplier and that they'd ship my order on 5 February. Today I received yet another email to say that yet another item had been delayed and they only expect to receive it 'on or around' 15 February, so they can only ship my order 'on or around 16 February. I emailed back to ask why they can't deliver my other items in the meantime? How do you run an online order/delivery site with all of these long lead times and constant delays. I've never experienced this with any other site I've ordered from. And if other sites experience delays they split your order and deliver the items that they do have. This is absolutely unacceptable - coupled with the fact that they don't reply to emails queries that are sent to them. Shocking customer service, but I suppose they can just blame it on Covid and assume that everyone will accept this excuse!! Wake-up call, Loot ... nobody believes that lame excuse any more!! When your service is bad, it's just bad!!!
