Closing an account: Checking or savings account

Venmo refuses to close the account associated with my email address. Despite calling and finally getting through to a human after multiple attempts, they refused to close it because I no longer have access though the phone number originally associated with this account. They were able to send confirmation texts to my email, but I can not receive the two-step verification to a phone number that is no longer mine. I would think they would understand this but apparently their concept completely confuses their staff members. They choose to play stupid games.
