Faded and unpolished silver chain do not buy any jewellery

My girlfriend ordered a chain and bracelet set for me , when it arrived we opened the packaging only to see a faded silver iron looking chain not even chromed or polished it looks very poorly made and cheap , something I wouldn't even pay R20 f0r , the person we ordered it from said we can not exchange it which is ridiculous I wouldn't even buy this chain for a dog I would atleast get a chromed one , I dont think anyone should trust the pictures in the books as it shows one thing and you get a poor quality replica
