Note that canceling most such services just prevents the service from auto-renewing at the end of your current subscription period. Few if any will cancel immediately and refund the unused portion of the subscription to you. If you then establish a new subscription before the old one runs out, this means you're paying double. This may not be that big a deal if you're you're currently paying monthly, but if you have an annual subscription with a lot of months yet to run, you might want to wait until it expires before setting up the new account.
