Pull it apart. Do NOT try and fill those gaping holes.
Is it the resin parts that are warped? They can be unwarped.
Pull the sucker apart, the warped resin parts, soak them in hot water (I use something close to boiling, tap water I find isn't hot enough). If it's a thick part you'll have to let it sit for a while so it heats through. Once it's warmed up, it'll be flexible and you can straighten the parts out, as they cool they'll go hard again.
Before pulling out the glue, test fit, lots and lots of test fitting. Get the best fit you can before you pull out the glue and try to minimise and gaps. If you get small gaps you can use a filler, but aim to have SMALL gaps, like, less than 1mm. If the gap is so big that you would consider using plasticard to fill it then you probably buggered up.
Do lots of googling on how to assemble forge world models, how to assemble resin models, etc.

I can appreciate not wanting people to waste their money, but they aren't going to learn anything if they don't try.
It's up to the individuals to decide whether or not they can afford to spend their money learning on expensive kits. Pretty much all
FW kits are expensive, so when it comes to learning how to deal with
FW resin, it's never going to be cheap.
