How can i contact support if my country's phone number isn't there?

ZMKS I've escalated your support case #21310524 and will check it's progress 

Oh, Hello GlennD. Thanks a lot for your quick reply. There's one particular case that bothers me the most - I can't add payment method. In fact, I don't even know is it in an 'open case' or not, because sales team's last reply was about a month ago. We want to 1) renew our subscription which is due in a month 2) add another one or extend current to a subscription which allows to have over 256 clients in one network (Hamachi). But we can't do it simply because we can't add 'payment method'.

Hi ZMKS, it looks like your previous posts were caught in our SPAM filter by mistake. I see that you have a couple of open cases with our support team, I would recommend continuing to work with them via email. 

Dear GlennD, could you tell us what "This discussion has been rejected due to other reasons" when you try to create a discussion? I created 3 topics, each of them was rejected with no exact reason given. The result is we have several unresolved issues for more than a couple of months due to unbearable way to contact your service and long response time via e-mail.

Hi akent, you can post your support question here and if needed we can create a support ticket for you.
