Gloria Vanderbuilt review: corduroy jeans

I have been buying your products for years and been very happy. I have others purchase them as well.
But the last 2 pairs I bought for first time were corduroy jeans. I wash tem after one wear and the belt loop came loose and then the next time the corner of the back pockets came loose and now they have torn completely down on seam no way to fix.
I really loved the fit but so disappointed in the product. I bought these at costco and have been buying them there for the last 10 years.
Is there something you can do about this. I would really appreciate it especially with your quality and name.
Awaiting for your response
Sincerely
Connie jean
