Well, I agree that 5 weeks is a long period and opening this thread is a good idea to get their attention, but it's not a good idea to start criticizing them from the opening post already.
You have to understand that this is not a big company. iRacing is, but you have to pay them monthly fees that often exceed the sum that you pay here once in a life time. They don't have the PR service and for what we know, they could all (3-4 of them) be on their vacation.
The other thing is how can they be sure that it actually was you who owned that account?
I don't agree with people accusing you of loosing the password and email address, I'm sure you already learned the lesson and won't repeat it again.
Be patient and persistent, but avoid being negative.
How come you forgot your web password as well?
