Bad Quality and workmanship

I bought 8 drops of eyelet curtains 18 months ago in different colours. The material is tearing out of the metal rings on all of the curtains. There is clearly no sun damage the curtains look fairly new at the back. It is just poor quality and poor workmanship. The volpes tags are still clearly in tact, and the curtains still look new other than the material pulling out of the rings. I went to 2 stores and also phoned head office. I asked if they could assist in fixing it. I did not even ask for a refund or replacement. They refuse to assist without a proof of purchase. I don't know about other people but I do not keep proof of purchase for things like curtains and clothes for that long. This is clearly their product and it is also still currently available in store. I would have appreciated assistance of some sort instead I received very bad attitudes from all of the staff head office included. Surely curtains are supposed to last longer than just 18 months therefore I chose to buy them from a trusted supplier. Unfortunately this is not true of Volpes it seems
