Scotiabank Annual Trust Fees

We have had our trust with Scotiabank for 10 years. We pay our annual fees of $498.80 every November via credit card. Other than updating the expiration date on the credit card, it has been a fairly streamlined process. This year they charged me $997.60, which is exactly double the normal amount. I have been sending emails for several days, but not getting a response. Just wondering if anyone else has had this happen. I will probably have to dispute with my credit card company, but was hoping to avoid doing that.
