I Hate Scammers

I get calls wanting to lower my rates in my credit card a couple of times a month. If I have time I'll play with them. Give them info that isn't real but close enough they have to stay on for a while. If you google fake credit card numbers you can find ones that will work for this. There also ones that visa and MasterCard set up for testing so they will ping their servers but not give anything other than saying they're valid Here's one of the links

Good hunting.
