Visa Tranaction Suspended for Unusual Activity

A Company that I ordered (phone call) a power cord from notified me that when they charged my Visa credit card, the charge was rejected. My Bank also notified me that the Visa card tranasaction was suspended because of "Unusual Credit Card Activity”.

The Bank said "We detected unusual activity on your credit card. For your protection, please verify this activity so you can continue making credit card transactions without interruption”.

I immediately called my Bank and approved the transaction. For security purposes, it seems, Visa suspends transactions from company’s that you have not purchased from before. I did not know this but I do support the policy. It is a good security protection from fraudulent uses.

I wish I had know above it before so I could call Visa to approve the purchase transaction before I made it.

Has anyone else experienced a transaction suspended for unusual credit card activity?
