Has anyone faced issue of Quickbooks deducting unauthorized money from your account using the ECS mandate

Hi there, @njacob.

Thank you for posting here in the Community. Let's get you over to the support you need to review the funds deducted from your account.

When you sign an ECS payment mandate for a loan, it gives authority to the clearinghouse to debit money from your bank account. Since you've mentioned there's an unauthorized deduction on your end, I recommend contacting our QuickBooks Support Team.

They have access and tools to investigate your account so that your information is kept secure and private. Our Customer Support Team is available from 9:30 AM - 6 PM IST (Monday - Friday).

Here's how you can reach them:

1. Click the Help tab in the upper-right corner.
2. Select Contact Us.
3. Enter you concern, then hit Let's talk.
4. Click Start a chat.
