Request additional accounts for Live Domain

We have two hosted domains in Windows Live Domains, lounge.cl and loungestore.cl. While loungestore.cl has a 500 account limit, lounge.cl is more recent and has only 50.

If it's possible I'd ask if you could please upgrade the number of accounts to 500. We currently use Google Apps. for lounge.cl and are quite fed up with their service. The idea is to consolidate lounge.cl and loungestore.cl under a single domain in Windows Live Domains and lounge.cl is shorter and cleaner.

The user in this thread had his account upgraded to 3500 accounts, so I hope that 500 won't be too much trouble.

Additionally, the Live Domains Admin Control Panel has the following, quite inviting message near the bottom of the page:

I know that Office 365 doesn't have user limits, but unfortunately it's way, way too expensive for us. I would greatly appreciate it if you could upgrade the domain.

Thanks in advance !

PS: I'm aware that the lounge.cl domain still has the old MX records that point to Google, however I did verify the domain ownership by adding the TXT record to our DNS server. I haven't changed the MX records because I need to create more users before I can replace Google's servers. I hope that this will be enough to prove that we own the domain.
