CBSA Client Portal Business Profile Address bugs

I've been calling CBSA for months, and it’s extremely frustrating that they cannot modify the business profile address. I’ve contacted the CRA many times, and they confirmed that the address is up to date. Somehow, the CBSA business account is not synced with the CRA account. A year ago, I had the same issue, and I was able to speak with someone who had the authority to fix it. Yet, when I called today to speak with a manager or someone with higher authority, they refused.

Are they really well-trained, or do they just want to waste my time? They even frequently hang up on me.
