I have been trying to contact the portal for many days, I have not received any feedback. Why is this happening ??
Hey,
Yes, that is correct - our chat is currently off. We apologise for the inconvenience.
More information can be found here:
Ok, I understand. Could you tell me where can I get answers to my questions? - I have been sending you an email for several days.
I can see that your email was sent yesterday, and as explained in the thread posted above: it takes about 48 hours until we reply to an inquiry.
