Yeah, this happens more often now because banks monitor suspicious transactions automatically. It’s annoying, but it’s usually for fraud protection. Still, if it happens a lot and support is slow, I’d honestly consider switching to a bank with better customer service and faster support response.
Yes, this actually happens quite often, banks sometimes block it automatically if they detect unusual activity, new location, large payment, or online transactions, it’s a security system to protect money, but it can be inconvenient. I also read on PissedConsumer Commercial Bank customer service page that many people share situations with blocked cards, account checks, transfers and similar banking issues, and the site is useful because people describe their experience, how they contacted customer service and how problems were solved, so before contacting the bank I usually read there to understand what to do and how others handled the same situation.
