Disappointed by the service

I bought a car last year December and I did not get my spare key, i kept asking for my spare key but my request was not met. Now that the consultant that was assisting me does not work there anymore it has become much more difficult as the manager said he cannot help me and that there's nothing he can do.<br> <br> I do not understand that and it is not acceptable that no one is willing to take the responsibility and accountability of the consultant that was assisting me when I took that car.<br> <br> I want that spare key. What happened to treating the customer fairly?
