Hi Andy,
Firstly thank you for having the confidence to place your order for a new system with us, please rest assured that it isn't misplaced
I wouldn't agree that the order process is confusing however we all always making improvements to make it as seamless as possible.
In answer to your specific points;
1) I will speak with the sales advisor who took your order, our 4 day priority build is so we can specifically guarantee/confirm the leadtime on your order. You placed your order today and its currently being built right now and will be dispatched on or before Friday.
2) We will always review this on a case by case basis and would never compromise the stability of your system in order to hit the 4 day leadtime. If we need to keep your system back an additional day you will be contacted via phone and have everything explained, I think the majority of people would rather this.
All in all prevention is better than cure, we have a dedicated team responsible for priority orders and contingency built in.
3) This is something that we can improve on, the email you received is automated (once the systems booked in) and is more suited to a normal 10 day build. Physically picking the stock right away is key to a priority system, if something was missing we would be in contact right away with an alternative or revised dispatch date.
Again thanks for taking your time to post up, ill be sure to look into everything and make improvements where appropriate.
Best Regards
