Last week, I urgently needed money to pay off my mortgage. When I applied for a withdrawal, I asked Nanya customer service if they could expedite it. They said, "Pay a 500 yuan expedited fee, use the priority data channel, and your funds will be in your account within 24 hours." I gritted my teeth and paid, hoping for a quicker payment. But after 24 hours, nothing happened. I contacted customer service, and they said, "The data channel is congested. Please wait another 24 hours." I waited another two days, and still nothing happened. I asked again, and they said, "Your application was misclassified as risky by the data system and needs to be reviewed again." Now, 10 days have passed, and every time I ask, they say, "It's under review!" I asked for a refund of the expedited fee, but they said, "Expedited service is provided, and no refund will be given regardless of whether the funds arrive." They took the money and didn't do anything, and they're so confident?
