Levi's poor quality and lack of customer feedback

I have been a great advocate and user of Levi's for many years, over the last few years I had found the quality of the product decreasing significantly. Same styles of jeans all tearing in the same place, I have attempted to provide feedback via their direct social media channels however get no real response ie I get an acknowledgement of my message, a commitment to respond and then nothing. Is a pity as it is a brand i held in high regard, similarly a lack of response to your committed customers is disappointing.
