How to cancel Celerity Telecom by mail
Start with your account details
Celerity Telecom will look your account up from what the letter says, so check the account number, the phone number or service address being cancelled and the name on the account first.
Write the cancellation request
State plainly that you want the Celerity Telecom account cancelled, further charges stopped and a written confirmation sent to you. Postbye sets this out in a ready English template (“Subject: Cancellation Request – [your name]”).
Mail the letter with a receipt
Post it by certified mail to Celerity Telecom in La Salle, Canada, using the exact address below, and note the tracking number.
Keep the delivery receipt
File the receipt with the letter. A Celerity Telecom charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Celerity Telecom cancellation letter goes
Celerity Telecom takes its post at Waterview Drive 42, R0G 0A2 La Salle, Canada, which is where a cancellation letter belongs.
The envelope is going to La Salle in Manitoba, Canada, so the postcode R0G 0A2 must be on the front.

Cancelling a phone or internet plan
