It may just depend on the rep you get. My rep was going to do everything in his power to keep me from canceling. I figured 30.00 credit each month for 6 months plus the to go feature for free was good enough for me. Call again and sound pleasant on the phone. It does work.
I am in the middle of a contract as well and it hasn't worked for me. I am going to call again and try the method described by penthos, but last time i threatened to cancel they told my my termination fee would be close to $250 dollars. If anyone has had success and is mid contract please advise
