On my last Discover card statement, there was a charge that posted on Nov. 30, 2010, for $1850.00 with the name Corporate Travel Brokers Wilmington DE next to the charge. I immediately called the customer service for Discover card and told them that I never talked to anyone at any company called Corporate Travel Brokers, and I certainly had never given them my credit card number to authorize anything. There was no telephone number to call listed next to the name of Corporate Travel Brokers on the Discover statement, so I couldn't even contact them and ask what was going on. The Discover card rep. put me on fraud alert, issued me another card, and said they would investigate. I haven't heard anything yet, but I was told it might be 90 days. Something should be done about companies who try to prey on people who have been trying to sell timeshares. That is the only connection I can see because I had past dealings with a company called Timeshare Express Services in Wilmington, Delaware, where I did give them that same Discover credit card number back in July of 2010. They were going to charge me $1850 for their services to sell my timeshare, but when I tried to cancel the transaction the very next day because I found out that they were not a reputable company, they still wound up collecting $472 from me through a technicality. I suspect that Corporate Travel Brokers got my credit card number through Timeshare Express Services, but those charges were NOT authorized by me.
