Customer service lines belonging to major companies that cost you money to call them.
The basic outline being ....We aren't doing a good job relative to something we promised to do for an agreed sum.
So to resolve this, you need to pay us to sort it and that payment is open ended while we keep you on hold.
And the PS to this is companies that strive to keep themselves distant from their customers via FAQ's / no reply emails / incomplete contact info.
The aim is a "no people" interaction service which forgets completely that customers are people. Sad
