Problems with a purchase or merchant

If you have questions regarding a merchant transaction or any product or service acquired through the use of your account, before contacting us you must attempt to settle the problem or dispute directly with the merchant. We are not responsible for any problems or disputes you may have with a merchant or in respect of a merchant not honouring or accepting any credit device. However, you may contact us to discuss disputes you may have with a merchant or with us with respect to a transaction or if you need more information about a transaction on your statement. We are not obliged to take any action for merchant disputes unless required to do so by law.

If you decide to contact us, write us on a separate sheet (or use a copy of the form provided on your statement) at the following address:

P.O. Box 9614
Ottawa ON

Or fax to 1.877.839.6262

Alternatively, you may call our Customer Service Associates at 1-800-347-6262 and we can assist you in setting up a pre-authorized debit.

Do not send the notice on or with your payment. We must hear from you no later than 60 days after the statement closing date of the first account statement on which the transaction or suspected error appeared. You can telephone us, but doing so will not preserve your rights. In your letter, provide all of the following information:

  • Your name and account number
  • The dollar amount of the suspected error
  • The posting date of the transaction in question
  • The merchant name
  • A description of the error and an explanation, if you can, of why you believe there is an error. If you need more information, describe the item you are not sure about

Merchant charge-backs are subject to MasterCard Rules and Regulations. Even if you have problems or disputes with a merchant, you are still responsible for the total amount owing on your account (which includes the disputed transaction(s)) and for making your Minimum Payments on time as required under this Agreement. If a merchant gives you a refund and we receive a credit voucher from the merchant, we will deduct the amount of the credit voucher from the amount you owe on your account.  If we agree to credit your account in respect of a merchant dispute, you agree that your rights and claims with respect to the credit are automatically assigned to us. In certain situations, you may be required to sign additional documentation before we can credit your account.
