Thanks to using CallZero, I was able to negotiate my medical bill from over $500 down to just $125. It really helped me save big—and relieved so much stress!

Jeremy Jun 4, 2025 v@ initial release

Love the premise but bummed it only works for USA numbers. I have a customer support challenge in France with SNCF and would love to outsource it!

Vincent C Jun 2, 2025 v@ initial release

This is amazing! I just used it to lower my monthly car insurance for 70 dollars a month
