Levi's India — Product quality Issue

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201301

I got 2 jeans when there was buy 2 get 50% sale going on.. I dont remember the exact date. Please refer to my number - [protected]/[protected] or email id [protected]@gmail.com to check the order details. I purchased it from shipra mall, noida (201301) if that can help.
I'm really disappointed with the black jean. I asked them at the time of buying that i do trust levis quality but black is the color that fades but they assured me that it won't. But unfortunately it did. From knee length it looks so bad that i dont even wear it now. I had hardly wore it 10 times. It seems like i have spent so much of money on duplicate product and my faith in you is also fading. I'm so sorry to say but if someone ask for suggestion about quality now i wont suggest your brand name.
Please let me know if you can be of any help to make it easier on me. Because i really was very happy buying it and with other orders also, but now i have second thoughts about your label. I have attached the pictures for reference. Please help me improve my experience with you, if possible
