NeilT - I have an RBC USD Gold Visa with my business name on it - not sure if it's strictly a "business" card, but it looks like it is. Is that what yours is like?
Um this has never happened to me.If you make large amounts of payment on a personal cc it'll always be put on hold for 2-3 business days before it's released. This happened to me so many times... cant wait for the mosaik to come.
