If she uses that account for auto-pay of her utility bills, phone, car insurance, etc, etc, she may have been trying to avoid the hassle of switching all of those billings over to a new account.
Which do you think would be easier, getting the Obamacare to stop the auto deduct from her account or contacting the utility companies?
Next, the car insurance should not be a consideration. She should have that paid up for the whole year to take advantage of the discount offered for doing so.
With the utility bills all that needs to be done is wait for the bill in the mail and then send a check.
Are you sure you are not trying to make this one more difficult than it really is?
