Customers using Zelle within their banking app have fallen prey to a scam where they send money for tickets but never receive the ticket; since the transaction is instantly done the scammer then closes their account and by the time the bank fully settles the payment the money is gone; banks in the Zelle network, and Zelle itself, have said do not send money to anyone unless you know and trust them; when money is lost customers are asking who should be responsible for replace the funds, should the bank refund them or Zelle; the relationship between the banks and Zelle is not entirely clear from the user perspective, with more frauds occurring customers are starting to ask more questions.
