    And I discovered that they play bait and switch and have no problems lying. This system won't let me give it zero or negative stars so I have given it one, but that is at least one too many.

    Very easy to setup 6 month 5.35% CD from cornerstone account

    I applied for an savings account online with this particular financial institution and was, ultimately, denied without a reason or explanation of why. It refused to release the reason(s) for denying the account application. I would NOT recommend this particular financial institution for any type of financial products or services.S

  • June 10, 2023 |

    helpful folks but not a frictionless process like Marcus or Ally.

  • May 22, 2023 |

    Transfers and external accounts all set up in three days.
