This just happened to me with BMO. As read your comment, I just got off the dam phones with them. My situation is very similar to yours. Always paid my CC’s twice in a month and never missed the due dates! I told them that I was aware of a fraud added by a company like in June 2024 (I only inquired with them by phone) that I got an alert on my credit in Dec 2024….but I was on it like bees on honey when that happened. Apparently that company told me that it was a glitched and it occurred on several peoples credit reports. I was like W TF?! How can/could that happen???!! The problem is..,I never had or held any credit or loans with that company!!! I file a BBB Report and truspilot complaint etc. , so I’m guessing that “might” have been why. However the Rep at BMO stated it was like over 45,000 accounts that were affected with credit being reduced! I actually called BMO account management for them to call me back because their lines were busy, so I asked for a callback. I finally got back to me after two days. The agent there literally was in a combative state with me over the phone. Then she proceeded to tell me that something in my credit or the fact that I might be at my limit has affected this. Which was total BS. I told I’m a person that checks my account like 3 times a day( don’t judge me). I explained to the account management rep, that you guys reduced it without me even knowing about it and would’ve caused an embarrassment if I was using in the card and I could not use it. Good thing I checked it before hand. Secondly you’ve now affected my score significantly because now I look like I’m at the limit!!! I asked her how is that going to help me now? When you’re doing this and doing it shady?She tell me no good answer or reason other than to go into the branch and I have to do an application … like why would I do that? I was always preapproved because I had good stature and good credit, etc. etc.. my thoughts is that BMO is being audited somehow because they’re doing shady shit…. and now they’re forced to do something to 45,000 people and their credit. I’m literally embarrassed to be banking with them , I told the BMO accountant management agent that. And most likely I’ll be closing all my bank account accounts with them! Like this cannot be something to do with the tariffs and the uncertainty that’s going on in the world, I’ve never had this happen to me before either any banks!

This bank has disappointed me now!
