Venmo Email Support
Venmo provides their best customer service over email. If you were hoping to talk to a Venmo agent live right now, on the phone or via live chat, this might be disappointing. But at least you know there should be a person on the other end helping you, and it may take less time overall to send a few emails back and forth.
Venmo Live Chat
Unfortunately, Venmo does not offer live chat as a channel for customer service at this time.
