Query: Disappointing

I ordered a GPS system, the cable and the dash holder for the GPS systemfor my son. Amazon broke up my order into 3 separate orders. The cable was delivered on a timely basis before Christmas, however, the GPS system and the dash holder were never delivered. When I contacted Amazon, they showed no record of the GPS system or the dash holder. Funny, they took my credit card, but said they had no record of the order. My son needed it for a road trip to Texas from Ohio. We waited until the night before he was to leave, it never showed up, so he went to Best Buy and bought the identical system and dash holder for $40 less than on Amazon. Buying from Amazon is taking a chance.....no more Amazon for us.
