SES Production mode is taking too long

I requested to enable Production mode on SES and I got a response to elaborate further and if I were to respond within 24 hours I would get a response back within 24 hours. Only the response never came. I have 18 hours (EU Time) until my deadline and no way of switching to another email provider because the DNS records are managed through my client and my client's business is closed until Monday (the deadline). It's such a simple website with hardly any functionality, it's just a sign-up form for a set of courses with a confirmation email. Is there any way of accelerating the process. I have looked into buying into one of the support tiers but that locks me in for at least a month. Is there no other way I can contact someone at AWS about this?
