I received an order for a large sum of money over the internet. We corresponded only via e mail. I ran the credit cards ( 3 ) through and the transaction seemed to be valid. I waited until visa put the money in my account before I used some of this money to order this specialized product that I did not have in stock. I also paid some long overdue bills with the balance. When the day arrived that I was going to ship the product, the customer contacted me and wanted me to send to Nigeria. I then started checking on the name to match the credit card through visa and found that they were fraudulent. I did not ship the products, I do not know who this person is and now visa is taking this large sum of money from my banking account. Since this is a commercial transaction, Am I able to be protected by the " holder in due course " clause? I haven't mentioned this to visa but have been doing some research on my own. Help Help Help. This will jeopordize my business if I have to pay all of this back. I have already lost over 1500.00 in withdrawals and bank charges! Also, unfortunately I am a sole proprietor. The product cannot be returned either.
