Levi's changes sizes again

I have worn the 517 for over twenty five years and Levi's exclusively over 50 years. Two years ago, the cut changed and all 517's were relaxed fit. Send back and change size because they were too big. SO I ordered the same thing but now 517's are "slim cut". Doesn't work on me, I need some extra room. Now the number is 557 for the relaxed fit and I get to pay the postage to return the wrong cut jeans. Shame on Levi's: they should not have changed these 2 years ago and then change again this year.
