Nissan Tokia - NO REFUNDS FOR THEIR ORDERING ERRORS

My mechanic tells me that I need a new pump for my Nissan Xtrail 2010.

I go to Nissan Tokai and I sat down with a consultant where we looked through the drawings and found the pump labelled "pump". I paid in full and waited 6 weeks for the part to arrive. When it arrived it wasn't a pump, it was a fuel level. Nissan tells me that even if the drawing was incorrectly labelled, they do not refund special order parts. I asked where it is indicated that this part is a special order item? They could not answer me. So I asked if I could be refunded and they refused. Now, I have had to get a LAWYER to get my money back. Very disappointed with Nissan!! Very bad customer service! Beware of Nissan car dealerships ordering parts on your behalf!
