You feel like we're making you look like the bad guy because you won't calm down.
Grab a beer or a coffee or your beverage of choice relax a little send a calm and collected (also polite) e-mail to Shoptemp or
Costello explaining your problem and what can be done to fix it.
You also have to remember difference in time zones just because your awake doesn't mean everyone else around the world is.
I'll admit I've had no problems with shotemp, I've only had perfect service but all the problems I've seen/read about on here have been solved and everyone has walked away a happy bunny.
Don't go all rambo "I won't be shopping with you no more!!1!!11!!" dodgey springs happen all the time, if anything it's the most common defect on any cart that's spring loaded it's easily fixable/replacable (granted you just bought you shouldn't have to replace it, I'm just stating a fact here).
I'm sure if you just give them a little bit of time everything will be sorted out with no problems.
