Re: Sometimes it's the customers fault
"They did call me and that was their point. Every time they phoned I said I was happy with the service I had before they could get into whatever spiel because I assumed it would be to sell me something extra when it was already expensive."
Which still makes it their fault. If they annoy you to the point that you are no longer interested in talking to them, they can't complain if one time it would actually be to your benefit. That is the entire point of the story of the boy who cried "wolf".
