check status of messaging.microsoft.com delisting

A customer's domain has been blocked by microsofts blocklist that covers outlook.com, live.com, hotmal and a few other mail services. I've sent through a request more than 24 hours ago and only received a first email notifying me that the case had been created. I then called Microsoft support who informed me that the issue had been escalated to hotmail support and that the turnaround time would be 3-5 days. This is not really acceptable for a business - most other blocklists at least offer a way to check the listing and see the reason.

Could a moderator please direct me to where i can check the status of this request online? Delisting Request number is SRX1223215212ID
