Short version - terrible customer service, poor photography skills, rubbish website, poorly run company.

I have experienced nothing but hassle and disappointment with Tempest. They did the photos for my graduation ceremony - obviously a special occasion. The pictures were not what I would expect from "professional" photographers.
None the less, I ordered online some photos as a gift. The website clearly states a 4 week delivery period. 4 weeks later (the week before Christmas) I called to see where the delivery was. Not only was I CONTINUOUSLY put through to the wrong people, when I finally got through to customer service I was told it "wasn't their problem" and apparently my photos HADN'T EVEN BEEN PRINTED YET, let alone in the post!
I said I wasn't happy and again I was told that it "wasn't their problem" and that I should have allowed extra time for Christmas even though that was already the case as I had ordered 5 weeks before Christmas, rather than the 4 weeks recommended by their website.
On yet another call I was told I should expect my photos to be delivered on the 28th of December. After Christmas. Brilliant.

It is now the 2nd of January 2013 and I STILL HAVEN'T RECEIVED THE PHOTOS! it was embarrassing enough having no gift for my parents on Christmas day, let alone still not having the over priced photos on the promised date of the 28th!
I have of course called Tempest numerous times during office hours only to be met with a recorded message telling me to call back between 9am and 4pm which is when I phoned.

This entire company is RUDE and behaves as though run by a pack of rabid monkeys. They have no idea what they're doing and have done nothing but made a poor photographic experience of a very special occasion into a long exhaustive nightmare. Useless.
