SCAM. AVOID.
Got a Tremendous prepaid visa through Eureka. It was a big mistake. In the UK they are pretty much impossible to use despite everything this scam of a company claim. Then in their FAQs they say to switch it to a gift card. However, for some weird identification process they send a code to your email that is only active for an hour but don't actually tell you they are going to do it, then its almost impossible to get anouther code. I wonder how much money this company is making through card that people can't use.
