Replacement parts

I have been trying to get one $6.00 replacement standard left runner for my Set It and Forget It since November 2007. I have a packing slip dated 1/7/08 Order # 00023817 that came with the right runner not the left! I have been trying ever since to get the correct part. I have talked with 4 different customer service representatives and one Supervisor beginning in the first part of April until the present. I have the dates, names and responses from each one telling me something different about the supposed ship date. I can provide these if necessary. Without this part I can no longer use this appliance that I rely on.

Thank you for any help you can provide in this matter with Ronco
