Bad costumer service example
Me and my mum ordered the home signal service from Three as we moved house and the signal was really bad. When the box arrived, it didn't work we called costumer service and they kept me on hold for 30 minutes, so I decided to call them back and their lines were closed, so I waited half an hour for nothing.
