Good Quality Alpaca, Poor Attention to Detail

My sweatpants arrived with a hole in the pocket. I sent multiple emails to customer service and never received any reply. Given the price, I was hoping for better attention to detail and quality control. The alpaca itself is warm and very cozy.

Amazing Alpaca

I have numerous alpaca sweaters and was thrilled to find these alpaca sweat pants. This my second order from Arms of Andes. My first order was an alpaca quarter zip top. I was so impressed with quality of the fabric and workmanship that I wanted some bottoms to go with it. I will definitely be ordering from this company again.
