I received a letter from my bank. It was from bankcard service department. I wondered what is this all about. The letter said “We temporary blocked your credit card because there was an inconsistent activity.” What is the inconsistent activity. I didn’t by anything unusual or expensive items. Is this some kind of scam? I have been paranoid about scam. Because I was almost deceived by telephone scam once not long ago. So, I called the bankcard service office immediately. And I found the inconsistent activity all about. I used the credit card to pay for skype credit more than month ago. I had a lot of problems at that time. My card didn’t go through for some reason. Somehow, the card company considered it was the inconsistent activity. I have’t been using my card since then. I didn’t even know that my card was blocked. Any way, It all fixed now. I feel better now knowing the card people watching card scam that well.
