Mr. Van Kesteren, if we are talking about win-back, the distinction is that this is not something that happens before the sale.
I agree with you 100%. The consumer can go from supplier to supplier to supplier, solicit the best deal, and then make his choice. But what we're facing in a win-back situation is that after the consumer has made their decision--and maybe they don't call the telephone company and ask them for their best deal--the telephone company, by virtue of having control of that customer, knows about the transaction, and they are the only one of the competitors who does. And then in a very specific and targeted way, they approach that customer after the sale has been made and roll out their best deal.
If you bought a television set from retailer X as opposed to retailer Y, you've made your choice, and the sale is done. Retailer X doesn't call you back the next week and say, bring the TV back and we'll give you a sweeter deal.
