Reliance Market — bed sheets

Address:

390002

I purchased 2 bedsheets from your vadodara reliance market outlet. At first time i purchased and opened at home it has one hole in that. So i go back to your outlet which is 9 km away from me. They replaced that piece. But when j washed it, i'm shocked.in only first wash colour is totally fed away. There are thousands of white shades in only first wash. Now what can i do?
