Sounds like a stuck port - I know you don't want to hear this but you are going to have to contact the moderators again. I am presuming you know how already since you've been in contact with them but just in case not click here and provide your email address, phone number and details of your problem.
I'm also going to presume that the moderators told you things like restart your phone, etc. as well and you followed them.
Hopefully this is something that will be cleared up soon for you. Assuming you did not explicitly cancel your previous plan then your number should still be "yours". What I mean by that is the porting request and process will cancel your previous carrier for you, you don't need to nor should do it yourself.
It won't hurt sending another message though. I do hate to say it but this is now "after hours" for the mods (normally) so you may need to wait for another response in the morning.
On the other hand, you could wake up to your number working too. Let's hope for that.
