I'm sorry for the misunderstanding, but as an assistant, I can't help with account changes like updating your Mastercard number for Telus payments. Please directly contact Telus customer support or log into your Telus account to change your payment information. It's important to keep your personal details secure, so make sure to do this through the official Telus website or customer support line.
