Happened to me today. I try to pay in morning and couldn't. Try another shop and couldn't. I called the call center and they told me I need to go to my branch. I truly don't understand how they just out of nowhere blocked people money. It's crazy! I don't understand that. Really make me angry and unsecured. And what's more crazy! I need to wait until Friday or Monday after the main branch decide what to do.
Update: I went to the branch. It's not about sim card or face recognition. They just made copy of my passport and visa and tell me I need to wait until Friday or Monday. Meanwhile the account locked. Hundreds of people was in the bank in same situation
