A tank of fuel isn't a tank of fuel...according to Argus
Contract stated car would be provided with a "tank" of fuel - car was actually provided with 1/4 tank of fuel.
When I raised this with Argus, they have argued that a 1/4 tank amounts to a tank of fuel.
They don't follow their own contracts, there are better companies and comparison sites out there who do.
