POOR QUALITY SUNBLOCK SELFLINED CURTAINS

U&G Fabrics your self lined sunblock fabric is of poor quality! We had on the recommendation of Concorde Interiors curtains made with your self lined 100% sunblock fabric for two very large windows both in our bedroom and diningroom. So four large drops. Firstly the fabric is so inferior that yellow streaks appeared after a short while. F ollowing your washing instructions the lining then turned black in the water! Imagine our shock. You replaced them with the same poor quality without providing any explanation as to why your fabric is inferior or why you used the same inferior product. Never once did you confer with us or explain anything. Now once again you provided the same washing instructions and exactly the same thing happened. Now you and Concorde Interiors tell me the client, who has spent thousands, there is nothing you can do? Why would you provide an inferior product in the first place when other sunblock selflined curtains are not reacting this way ? I have conferred now with other professional interior designers who are all in agreement. You should never have replaced it with the same inferior product and that this is unacceptable. I am left without any resolve just treated with disdain. Is this your manner of business? I find it unacceptable and unethical. No client purchasing in good faith should be left in this position. UG Fabrics will never have my recommendation. Whilst all is good thats fine. The moment theres a problem with their goods they dont want to know. They had an opportunity to resolve this but decided that the thousands of rands I had spent was of no regard to them. Why use an inferior product when they could have used a product of quality? Other fabric houses and interior designers wete horrified to see this and agreed the product is of poor quality in comparison to others. Why do you sell this product to interior designers to use in residential homes?
