I'm not saying they're dodgy but do due diligence on 'CB (0r was it CD?) Wealth'. An Englishman calls up within a couple of days if one contacts Cathay Du Pont. The number being called from is a local mobile it seems. But a digitally altered message greets one when one calls back. There are a couple of variations on CB Wealth to be found on the Internet. Good to see the UK FCA has listed SFL as a likely scam. More than likely!
