With respect to Mr. Van Kesteren's point earlier about winback, you said it's common practice that a business would put its best offer forward automatically. It is also common business practice that offers or bids are typically sealed such that the competitors are not aware of the other bidding.
Would not the large telco companies be aware of the incoming competitor offer on the day the switch order is made by a potential consumer? Wouldn't they know right then what was being offered?
