In a former life we used to be hauliers and the secret to fuel cards was to have 2,3 or 4 companys on the go at once because they start of at a good price per litre and then go up month on month ,we used PCS fuelserv,CH Jones ( keyfeuls) , and another small company That I cant remember the name off so use one for a month or two when the price goes up, phone them complain about how expensive they are , stop useing them and use another within 30 days they send you a letter saying how their price has gone down then use them again and so on
Play them at their own game!
Hope this makes some kind of sense
