Recieved the wrong oxygen sensors in my order.

[kvknn_33]

I ordered a set of 4, o2 sensors for my 2002 Ford Mustang. I recieved the order however all 4 of the sensors are the same, with the same part number. 

The problem is the sensors should be different with 2 upstream right bank, and 2 downstream left bank. All 4 should be differently keyed.

The order said it was a "set."

This, along with the higher higher for  the Ford motocraft brand should come as a distinguished "set" (as these where indicated) but all four came as one sensor with one part number.

 I would like a refund.

Correction:  ...1 right bank upstream, 1 downstream right bank.

I left bank upstream, 1 downstream left bank.
