I ordered a part back from Sears for their Kenmore vacuum cleaner. This was in July of 2006, since then I have not received the part. All I get on my order form is... product on back order until such and such a date. On that date another, "Product on back order until such and such a date." Well this has gone on since JULY!! I have called the parts service and gotten rude replies. I tried to talk to the manager of my local Sears and got no where. Is there ANYONE I can get a hold of to resolve this matter?

Thank you
Terry
