Google / fraudulent charges on my credit card!!

I received an email from my credit card company advising me that my account had been flagged due to unusual charges. I looked at my online statement and to my disbelief, saw over 75 purchases made on 03/20/2017 and 03/21/2017 of $2.99 from Google. All of the charges had an asterisk* after the word Google, with a set of numbers and some were followed with g.co/payhelp # CA 94043 USA. When I contacted the customer service department of my credit card company, the agent stated that there had been over 260 attempted charges!!! Most $2.99 and a larger one of $74.00. My credit card company did an excellent job of taking care of the problem on their end. I have no idea how these thieves got my card number but I was advised that I was just 1 out of numerous customers who called with this exact problem. Obviously there is a large scale scam going on and they are using your company to steal money from people who actually work for a living. My account had to be closed, a new card mailed out, and I have to wait until they conclude their investigation to be able to use it again. This is very inconvenient for me but most importantly, I hope you can get to the bottom of this scam so it does not happen to more people in the future. This could potentially cripple someone who does not have a lot of income and/or children to feed. You are one of the largest companies in the world with endless resources at your fingertips. I hope you use some of those resources to combat this fraud. Also, a tip off may be that people do not make 260 charges of $2.99 one right after another. Thank you for your time.
