This definitely is a good idea, couple years back when I closed my account with Bell, there was supposed to be 3 or 4 dollar refund payable to me, but bell people said it is less than certain amount (5 dollar or 10 dollar) that they cannot refund for to handling fee.
I fired CCTS, within a few days a bell rep called me and politely refund me the money, funny she even asked how I am aware of CCTS, lol
