Thanks for joining this thread, karen10.

To have your customer assignments setting turned off, you'll want to continue getting in touch with our Customer Care team. They'll be able to pull up the account in a secure environment and assist you with turning it off.

They can be reached while you're signed in by using your Find answers and get help icon.
 

Be sure to review their support hours so you'll know when agents are available.

If you're not able to get the customer assignments option turned off, request a case number, and update me here in this thread.

I'll be here to help if there's any additional questions. Have an awesome day!
