I acted in good faith, it just didn't work out and I feel bad about that.
That isn't how it works, there were no back orders because unlike some suppliers, Lencarta doesn't knowingly make any item available unless it is physically sitting in the warehouse waiting for someone to buy it. Don't take that as a dig at others who do take back orders because it isn't, it's just Company policy.
I admit that there were more orders than I expected, but I also expected that they would go out on time.
I understand what you're saying here and that's almost a fair comment. The website was completely revamped in December, since which time it's been plagued with various problems including very slow loading - believe me, these various problems are no more acceptable to me than to you.
The warehouse updates the various orders on a daily basis, until they have done so the order stills shows as 'processing'. Problem is, sometimes they've tried to do this but the slow performance has made it impossible to get into the backend, so the orders haven't been updated. It would probably be OK next day, or even an hour later after they've gone home for the day, but it's pointless sending an automated email the day after, a bit like the letter I had from the DVLA telling me that my driving licence would be arriving in about 2 weeks, a few days after I got the driving licence

Didn't you get the automated "Thank you for your order" etc with details of your order and the amount paid as soon as you paid? You should have done. Because that's automated I can't mess it up, so I'm confident that you did get it
Oh, and a heads up - Because of the slow response on the website, our webmaster is in the process of changing it to a brand new, superfast dedicated server which is absolutely guaranteed to solve all the problems - I hope! I believe that this will be over the weekend some time, so the website may be down for a little while but, like the 6 million dollar man, will be faster and stronger than ever before.
