I am not happy about it and would like to have an explanation on this

however as you said this doesnt change the situation as we are bound to pay the invoice even when we are not informed about the price change.
thanks for everyone
This change is for everyone, like I said before. Because of that we can't change anything about that. The mail informing you was send to your address but it doesn't seem to have been delivered or it was missed.
Aside from the mail, the information about the change was also on our website and in a dedicated topic so it is available at multiple sources.
