No offense taken here.
To start off, there are almost no pattern arfs on the market in this price range. Matter of fact, there are hardly any kits that you can build in this price range. Shoot, the one''s there are, you can't get.
2M pattern kits or arfs are a rare thing unless you are willing to pay 2500 or more for the airframe.
So therefore I would fix the ones I have and just be upset with the company.
Here's another example for you though.
I have many arfs. Here's a list of a few.
Dave Patrick Extra. Straight, good quality kit! $429
Hanger 9 Cap 232 1.40 size. Wing was warped. Pulled covering off bottom and glued the joints together properly and straight. Still decent quality. I think it was $350.
Hanger 9 Edge 540. Straight, good quality. Like $350.
Hanger 9 Extra 330L 33%. Straight, big, and great quality. I think it was like $750.
These IMAC style planes are a dime a dozen. They can be found at any LHS generally.

Now I have this Evolution. It's a rare thing to find a 2m pattern ship for this price. Yes it has it's issues. But you can't find this type of plane anywhere. So I'll fix it as I need another airframe in the air as I have lost 3 this year.
I am going to call ultra rc here shortly as that's what I was told to do. I'll see if I get the machine or a person.
