Help after enrollment on training

Probably this is not the best place to ask, but I could not found any other (besides email to which was not answered).

I filled the form to training (02/08/2017), paid with no problem, and then… nothing!

No confirmation email, not further instructions. I dont know even if I need to use any software to attend to, if I need an environment create, which URL I should use!!!

And most annoying : no contact email, skype, wherever

Can anyone help me on this?

thanks in advance,
