How hard can it be to deliver a computer?

Given my 3 year old desktop at home melted I bought a new Mesh computer.
Firstly I had the very helpful barclaycard fraud detection squad stop the transaction phone my work voicemail (despite the message saying I am not here) which then took 1 hour to sort out with them and with Mesh.
I had planned to work at home tommorrow, specifically to be in for the delivery of the new machine (more critical now as my work machine is on the way out). They phoned me at 6 pm today to say "sorry there has been a slight delay". The slight delay is actually 7 days! Apparently the defualt excuse is that "we are waiting on the hard drive from the supplier". A bit odd that, not an uncommon part.
So having rearranged meetinegs etc I am now left with having to move stuff next week. I have no machine, and they already have the money. I picked Mesh because I bough my in-laws a machine a while back and I was impressed, but thinking back that was a week over too. Could it be part of the business? Take the money, delay a week must be some profit in that?
Anyway, noit sure if that will inform anyones buying decision. I am sure the machine will be lovely next week, I get less of a clash playing crackdown as that's on its way too now.
Anyway up to you, customer service atleast they told me. hmmmm not great.

*UPDATE This I actually good, but could have been tricky. My machine has now been delivered only one day late. i.e. It came on friday (today). This is fantastic news, and I am lucky Jan was in.
So Mesh are back in my good books, but they did set my expectations in a strange way :-)
