Avoid Mr. Zu. Dishonest supplier and pure breach of contract. I have 25 years of experience in textile, but never experienced such arrogance. We agreed on 100 pairs bulk order. He charged a sample price 5 times higher than other factories, promising this cost would be deducted from the bulk order. Sample quality was nice, but when I asked for the bulk shipping price, it was more expensive than the products. As an experienced buyer, I told him I would arrange my own shipping to avoid these inflated costs. As soon as I declined his shipping, his attitude changed completely. He suddenly claimed they had no time for my order. When I offered to wait, he refused the order entirely, claiming it was "too small"—directly breaking our agreement of 100 pairs. He also aggressively refused to refund my sample money. He even insulted me by claiming his boss "doesn't speak with small producers". They only care about massive buyers. Absolute scammer, reporting to Alibaba.
