This can depend on what version of Binance you're using, and how hot the crypto market is. The USA version of Binance (at Binance.US) has the worst reputation for customer service. However, if you happen to be using the UK version of Binance (at Binance.UK) or the Australian version of Binance, you may get better customer support. If you're using the USA version, be aware that there are numerous complaints about Binance taking weeks to respond to support tickets. And if you're using Binance at a time when the crypto market is going nuts, they're going to be absolutely swamped with support requests.
Unlike the Australian-based exchanges I've reviewed where you can always expect a response within 24 hours, with Binance.US, that's unfortunately not the case.
