CIBC Branch with ATM

I have a non-registered GIC product that, according to the contract, pays interests annually. Last year I withdrew my due interest without any problem with this same branch. But this year when I walked in, the staff refuses to give me my interest, which was already sitting in my account earning nothing. They told me that I cannot touch this account until it is mature. (it turns out that they got it mixed up with a similar registered GIC product). I was really surprised and insist that this product pays interests annually. The staff in this branch treated me rudely, talks as if I knew nothing about this product and was making trouble. Although in the end after talking to their headquarter by phone they gave me my money, the entire process was handled rudely and carelessly. I didn't even get my receipt for that transaction. I can give my testimonial that the staff there is exactly the opposite to "putting customers first".
