A number of people report getting a check from American Express to compensate for Marriott Bonvoy points which were not properly deposited. Apparently this is for an old Marriott card from years ago.
We’re writing because we’ve enclosed a check to refund your account listed above…Because of a technical error, Marriott Bonvoy® points you earned were not properly deposited to your Marriott Bonvoy® account…To make things right, we’ve enclosed a check as reimbursement for the value of these Marriott Bonvoy points…
Keep an eye out in the mail if you’ve had the Marriott card in the past.
