I received a call on December 23rd telling me that my account was frozen due to an overdraft. ?!?! Apparently Venmo has been making unauthorized payments to companies since October. Since I only use Venmo to send payments to others, I didn't know my account was in the negative. When the very nice customer service associate ask me to refer to my account page, it still did not show that my account was in a negative balance until I attempted to make a payment. Shady. Venmo would never call me?!
