Phone number comes up as Vacation Tour and Travel out of Conway, Arkansas when you google it. They left a message saying "it was regarding a transaction on a credit card ending in # xxxx. Please call back before 8:30". First thing that grabbed my attention was she didn't say what time zone the 8:30 referred to. Didn't give her name and said to call back at a 1-800 number, (which does not google to a company name), but she gave no card name like Visa, Mastercard. This is a scam. If you call back I'm sure they would try to sell you a timeshare to a condo in Little Rock.
They called and left no message. I called the number as I mistook them for a neighbor's cell. Was surprised that they called from Arkansas! I got their answering machine.
They claimed to be a travel agency. The wanted my cc info to book me a trip at an outragously cheap price. They had my choice hotels id number. They would not email me info. They claimed they did not have internet access.
Someone from phone number 501_329_5434 called me twice but I refused to answer thinking it was some kind of scam. I decided to Google the phone number and see other people are having the same problems so my suspicion was confirmed,don't answer and don't do anything regarding that phone number. Be careful and smart about soliciting phone calls.
