I have been using Access Bank since 2017 during my NYSC, and their USSD transactions are very reliable,probably the most reliable I have used.In April, I sent some money to a customer. Although the transfer was successful at my end, she said she hadn’t received the alert yet. I told her to give it a few minutes. Just five minutes later, she called back to confirm that the alert had dropped.Access Bank has always proven dependable. I trust their service.
