We would like to make the transition of your telecommunication services from your previous carrier as convenient and trouble-free as possible. To ensure the billing portion of this process is completed properly we ask that you please contact the billing department of your previous carrier(s) once your services are transferred to Allstream. Even though they may no longer be providing you service, it is best to confirm that they have stopped billing for services they no longer provide. This notice by you will prevent any continued billing, thereby preventing double billing errors. Be sure to wait until all services have transitioned to Allstream before canceling service with your previous carrier.
