Rant and rage until you get what you want. Make a scene if you have to(they really hate that, someone might see or hear what happened). I think that at the very least they should compensate you for you losses and upgrade your tank since it was thier bad advice that caused this whole mess.
On another note(and I know I'm just being a mom here) try to think of this as a learning experience. Believe me, we all have gone through simuliar situations like this in the hobby. It happens to all of us at one time or another. Hang in there! It is only a week. Of course if you make the scene now you could end up with something better like right away.
