Silly me, why didn't I think of using my phone.
I'm not afraid of making calls. I've made calls to at least 3 cgn sponsors for more pressing matters. I've waited a whole day to try to get through to CFOs in the past. It's a non-issue.
If you made the effort to use your brain cells you would know that e-mails offer the advantage of being able to keep records.
E-mail are sent instantaneously and they also give the responder the liberty of answering on their time when it's convenient.
This is also a way for me to test the waters with different dealers as I'm fairly new to this hobby.
In my case, it is now clear that they didn't think it was worth the time and effort to reply I guess until I posted in this sub-forum.
