Licence & Invoice problem – urgent

hello,

we got recently billed for the pro version, however we didnt recieve the invoice like last year on our email. I tried to login to boldgrid but it says that the email address couldnt be found. I tried couple of other emails that we usually use thinking it was a mistake, but non are recognized by boldgrid. I tried contacting over the plugins premium support but I received nothing. I also ised the contact form on the website.

This issue is quite urgent and we need your assistance in this matter. please how to proceed.
