How do I contact DesignSpark support team?

I was receiving support through a support ticket using the method provided in the URL.
(an unresolved case).
URL: https://designspark.zendesk.com/hc/en-us/articles/212523525-How-do-I-contact-DesignSpark


However, I have been unable to access the page in question for the past few days.
What steps should I take to continue receiving support?
