I no what ur saying i personally  have only a debit card and haved asked if he would accept that because  u can only debit money wen its in ur account it hasnt got a credit limit and its not linked to my salary account it linked to my other account which means all i would do if this was genuine was tranfer the required amount every fortnight that way they can only have what in there  but am with u with it not sounding good as have yet to receive a reply
