When you are connected to Visa, press 1 for English, 2 for Spanish. 

If you are a Visa customer press 1, if you are not a customer, press 4 for "other inquiries."

Here is an example of how a conversation could start (or you can just wing it!):

Hello, I’m [your name]. I’m a concerned [Visa customer/shareholder/consumer] calling from [your city/state], and I would like to speak to you about the need for Visa to report irregular purchases of guns and ammunition to relevant law enforcement. 

Most mass shootings are committed with weapons bought via credit cards like Visa. For example, the Pulse nightclub shooter used six credit cards—including three Visa cards—to buy tens and thousands of dollars of guns and ammunition. These erratic purchases with intent to kill should be easy to spot and report. 

The recent comments from Visa's CEO comparing buying a gun to buying a soda really concern me as a [Visa customer/shareholder/consumer]. Sodas don't kill people, guns kill people. 

I hope Visa will do everything in its power to stop the next mass shooting before it happens. 

Thank you for your time. 

Be friendly and polite - the person picking up the phone will find it hard to ignore you if you are polite. 

Don’t feel like you have to answer any specific questions if you don’t feel comfortable.

Tell the person that you’re a member of a global organization called SumOfUs, which runs campaigns to hold corporations accountable. Tell them you’re calling as someone who is concerned about Visa's role in enabling mass shootings. 

No! Visa cares what members of the public think and you don't have to be an expert to let it know you're concerned. 

It’s ok to say you don’t know. Or you might want to say that you will research the answer and contact them back with more information. 

The line may be busy - sorry about that. Please try calling again during office hours.
