A lady bought a cordless phone from us last week. The next day she came complaining that her phone wasn't working. We checked it out and found that it was working properly.
The next day she showed up again and ended up arguing with my boss. They decided that the best thing to do is to send someone at her house.
The 'repair guy' connected the phone and when he picked up the handset and dialed a number he heard a message on the phone:
"Please top-up your EasyLine account to make further calls."
