Luno support sucks

The platform is Awesome but the helpdesk is absolutely pathetic. I've recently changed phones, and in the whole process, my account was locked. I understand that they are very strict about security and I admire that. What I find absolutely unacceptable is that I have been struggling for two days now to get a response. Their policy is two business days, sure, something else I can respect (Although the world moves at an insanely fast pace, two business days equities two months in 1990) This is midday, day two. They offered to call me about 30 minutes ago. Still, I am waiting. As I client, I really don't feel a sense of urgency with them. They'll drop an email and then go quiet for hours again. Kind of like a runaround...
