In Person Only.
I contacted them about the 9 month CD. This was their response. "My name is Cade W. and I am responding to your online inquiry in regards to our Certificate of Deposit. Currently the only way to open these accounts are in Person and one of our South Dakota branches. If you do not live locally we hope to have an online account opening process ready to launch in the somewhat near future. If our rates continue to be awesome I would be happy to e-mail you when that time comes."
Run From This Bank
Very disappointed with this Bank & their CS as they offered NO resolution to my issue! Unfortunately, after paying off the balance I received another statement for additional payment. I feel this is an error as I paid off Loan in FULL. I left a msg on their website to dispute the extra charges & no one contact me.. Very BAD experience with this Bank.. I do not recommend One American Bank to Anybody.
