Hello there, @Darielyz. 

I understand the hassle that this caused you. I know that this is not the kind of experience you expect us to deliver. I’d love to help to get this sorted out so you could get back to business. 

I just wanted to let you know that my colleague responded to your other post. In order to keep the conversation streamlined and provide you with the best resolution, I'll ask that you post any follow-ups there.

Just in case you haven't been notified of the new response, here's the link: https://quickbooks.intuit.com/learn-support/en-us/banking/bank-account-not-found/00/956096. The rep offered another solution for his client to update the phone number.
 

Drop me a comment below if there's anything I can help you. It's always my pleasure to assist. Have a great day ahead.
