Query: It is not the seat you think it is!

This car seat SEEMS to have everything that you would want--longevity, comfort, price...but such is not the case.The straps are VERY DIFFICULT to tighten while the seat is rear-facing. I had to pull the slack from behind the seat in order to get my daughter safely in the seat.(She is 11 months and 21 pounds) Why should I have to do this and how would I go about it once the seat is forward-facing?The straps also twist constantly making an already frustrating situation worse.I thought I must be doing something wrong until yesterday when I could not get the buckles into the lock! The lock was clicked as if the buckles were allready in except that they were not in! I had to fool with it for a long time to "unclick" it so that it would accept the buckles. (Yes, the puzzle pieces were fit together properly-that was not the problem) Without the harness fully locked, this is useless as a SAFETY seat. It is going back to the store today.
