Keep getting emails about item in cart...

[defru0]

Two or three times a week, I get an email saying "don't miss out! there is an Item left in your cart!" and shows the last Item I purchased. I have changed my notifications, unsubscribe every time I recieve one, and have even called customer support. They said there was nothing in my cart, and they'd make the notifications stop. They  havent...what do I do to egt them to stop?
