I'm trying to summarize success stories mentioned in this thread.
From @TC610
It never hurts to ask - retention is a big YMMV. If you don't like the offer given to you when you call for retention, ask for a better one. Scan through the thread (use the search bar - reading through 130+ pages of posts can be time consuming) to see what others have been offered. Please post what you've got if its better then whats in the WIKI
