I bought the 10 Speed Osterizer Blender model # 6629 from Fred Mayer store. There was $10.00 rebate from the company of Oster. It has been nine months passed and called them several time to their toll free # 1-800-334-0759, but they always giving excuses and excuses. I never get back my rebate back. I would really like to know the other customers to be aware of the their fraudulence activity.
