Are you sure that you've passed app stepes of verification? Your ID pics, your bills, nudes etc... Those KYC bullshit is getting harder those days. I'm pretty sure your problem is about it. Otherwise there also might be some restrictions about your country.
Yeah, there is zero chance that you actually got through any (or finished for that matter) the KYC stuff in order to go ahead with buying Bitcoin with them. We all know it sucks, but I wouldn't blame the company when it comes to KYC regulations. As these are regulations which are imposed by governments to track who is doing what, as they're nosy and they want to know what's going on.
I'd reconfirm with them with their customer support if you actually finished it. Send some screenshots of the limits page.
