Honestly, slow replies from childcare admins are quite common here, emails especially tend to get lost or deprioritised, so if it has been more than a few days, calling the centre directly or just walking in tends to get a much faster response. If it is a licensing or registration matter that is dragging on for weeks or months, you can actually ask to speak to your assigned officer's manager directly and mention how long you have been waiting, which usually moves things along. ECDA is technically the escalation path if the centre itself is unresponsive, though some parents feel their follow-through is inconsistent, a bit hit or miss depending on the case. On balance, the most reliable approach seems to be phone or in-person first, then escalate in writing if needed so there is a clear paper trail.
