I used to have a fair amount in a Checking account there. They weren't paying any interest and that wasn't an issue until the last few months when many others started paying a few percent.

Gradually, I began to pull money out, a few hundred at a time. Transfers were initiated both from within Chase (pushes) and other banks (pulls).

I kept enough there to pay my CC bills and cover checks in case I needed to write one.

Then for no explanation, they started blocking transfers, both in and out. I tried to set up a pull from within Chase and it went to 'Pending Review' , then showed Rejected. This happened a few times I'd get a phone call from a suspicious phone number where they asked questions I wasn't comfortable with. The first time, they ended up approving the transfer, the second time, they refused and would not tell me why.

The other bank made no difference. Tried several including Citi and US Bank

Complaints filed with CFPB went no where, still no explanation.

It can't be any kind of limits as I didn't do more than a few and only for small amounts. There have been no bad checks or other problems. Account had never been overdrawn.

Credit card accounts have not been affected ... yet.
