Loyal Dell customer, feel like I was misled

I have been looking on the market for a new desktop PC for work, and as with my previous 4 machines, I went with Dell because I like the build quality and they don't seem to come with bloatware like other companies.

I put an order in for an inspiron desktop last night as it said on the Dell website I could have it delivered today, and I took time off today from work to do things around the house so I could receive the delivery.

I was texted last night to say delivery was expected today.

It is now the afternoon and wondering what time it might arrive, I followed the link to track my order and it says my order is 'in production', and expected delivery is the 20th of January, 9 days from now.

I would not have placed this order if I'd known it would be this long and feel like I was tricked into ordering it. I would have looked at buying a machine on Amazon where delivery schedules have always been on time for me, or a physical store instead.

I'm frustrated I've wasted a day, and there was no text or email update to say the delivery was pushed back.
