Continuing my subscription after it ends

Hello everyone. I'm looking for some advice. My subscription expired a few months ago. Unfortunately, I didn't notice. Now, after some time, I've tried to renew, but I can't find a renewal button on the website, in the developer apps, or in my subscriptions. What should I do in such cases? I contacted technical support, but haven't received a response. Thanks in advance.
