I had a frustrating experience with Binance when they locked my account and asked for address verification. Turned out I had two accounts, and my documents didn't match up. I had to manually withdraw my funds, which was a hassle. On the bright side, their support team was very helpful and professional. The whole process took 2 days, which was longer than I hoped, but I appreciate their assistance. 3 stars for the inconvenience, but kudos to their support.
