Hi -- Events would certainly point to the fact they are using stolen credit cards to cream off money onto their own prepaid cards that will probably be held in fictitious names. I bet that your store is just one port of call, with them visiting as many stores as possible on their rounds, to clear the stolen cards available balances and minimise their chances of getting caught.

Report this to your local Police who will arrange for some plain clothes officers to be around at the time of the transactions, if they are innocent they will have nothing to fear, but whatever you do leave it entirely to the Police.

I work for a convenience store and mostly do night shifts. For the last 5 to 6 months, we get two customers (black guys) who come in with their prepaid cards. In a single nighy, they usually topup their prepaid cards twice on the pay point with the highest amount (i.e. GBP 498 + 498). What bothers me is that every time they come in, they pay it with a credit card (which they ofcourse never show to the member of staff). If sometimes we are experiencing paypoint connection problems, these guys remain very calm and composed and oftenly guide our staff how to carry out transaction. They even leave their money with us and tell us that they'll come later to topup again, if the paypoint is not topping up. Can any one help me what's going on? Thanks
