How to cancel Triangle Rewards by mail
Find your account details
Triangle Rewards will look your account up from what the letter says, so check your member number, the name on the membership and the renewal date shown on your latest invoice first.
Put the request in writing
State plainly that you want the Triangle Rewards 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]”).
Send the letter by certified mail
Use certified mail for the L3C Welland address in the next section, so the post office records the delivery. Write down the tracking number.
Keep the proof of delivery
Once the letter is delivered, the date on the receipt is the date Triangle Rewards was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Triangle Rewards cancellation letter goes

The postcode L3C belongs to Ontario, Canada, so this is where the envelope is delivered.

Cancelling a membership
Memberships renew on the anniversary of joining and may be cancelled at a counter, online or in writing depending on the organisation, so a written request names the member number and the end date.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
