I made a car rental reservation on XXXX/XXXX/15 with XXXX XXXX for an upcoming trip on XX/XX/XXXX-XX/XX/XXXX. I paid {$210.00} for the rental. Today I received an Ad from XXXX advertising the same product for the same time period for {$150.00}. I called XXXX XXXX and asked them to please refund the difference. Needless to say I received a run around. I contacted my Credit Card Company to explain the situation and that I would like to use their " City Price Rewind '' benefit. Citi told me that the benefit does n't apply to Car Rentals. My question is why is this purchase any different than any other purchase? It seems to me if a company offers a lower price on an unused product, they should honor their new advertised price.
