Why is Binance not letting me buy?

I'm a bit frustrated right now. I've been trying to buy some cryptocurrency on Binance for the past few hours, but the platform just won't let me. It's like it's blocking my transactions or something. I've checked my account balance, and I have enough funds to make the purchase. What could be the issue? Is it a technical glitch, or is there something I'm missing? I've tried reaching out to Binance's support team, but they haven't been very helpful. Can you help me understand what's going on and how I can fix this?
