Cyber Metals Boksburg - inferior silver

Purchased their minted bars & rounds in 2013 with an agreement on a buy back policy, they have since decided to only sell internationally minted coins from recognised refineries basically leaving me with R160,000 of s**** silver which is unrecognised by the industry. when I enquired to exchange it & upgrade gold I was offered s**** silver costs as they had decided to change their business model. in my opinion they are not a an honest business & if I were to choose a bullion trader I would choose one with references from Google from satisfied clients which they have not employed a s a plug in on their website for what has become obvious reasons
