In late August, we received a bill for a free car kit, which had come with my mobile phone. Not realising that ‘free’ meant that you had to pay for it, I rang and explained that the salesperson had actually offered us two free car kits but when I told him we only had one car, he offered a new car kit for my new mobile and a $50 credit, in lieu, for Nigel’s new mobile. Now here I was staring at this bill for $49.01 for the car kit ………. and no sign of the $50 credit.
