Had some guy and his brother months back try to buy loads of stuff from our shop was over 300 pounds worth of stuff there payments wouldn't go through they tried numerous times took some items back untill they gave up they came back today with there dad same thing but this time it went through the cards are visa vanilla cards which is like a gift card/ bank card it's pre paid and has no chip so has to be swiped or keyed in seemed Dogy to me as they all had one and the guy got really angry when it wouldn't work last time due to lack of funds
