Treat a customer like a ********

I went in to a Markham branch today to get my account which was blocked due to a late payment. On the assistant calling the call centre he was told that there's a note on my account and transfered, they then said that they need to do a forensic check as payment where made from multiple bank accounts into my Markham account. Yes those are my accounts and since when is it ********** or ******* to make a payment from multiple accounts??!! I am am Actuary and feel highly ****ed off by Markham who views me as a ********... Disgusting service
