I signed for an upgrade to a 6 cylinder car from XXXX XXXX for an additional {$140.00}, but I did not get a 6 cylinder car. They gave a 4 cylinder Corolla. I asked XXXX for a credit to my credit card, but they refused. When I complained to Penfed Visa, my credit card company, they refused to give me a credit without a credit memo from XXXX.
