DOES ANYONE KNOWS OF A "FREE REVERSE EMAIL SEARCH?"?

I have a question. I need to find someone's number and i only have their email. I already found the city that they live in, but i need their phone number. And obviously i can't pay because i don't have a credit card. Does someone knows of a FREE website? Or do they have like a spokeo account where they can search that person up for me? Please and thank you. This is very urgent..
