Kulula.com Has Gone Awol With My Fully Paid Holiday Package

Booked a holiday package for me and my partner for April 1-3 2020 with Kulula.com, only for Covid-19 to strike and level 5 was put into effect. We had to put the whole thing on hold, I got correspondence from an agent informing me we had to book for new days but due to covid we were unsure for how long the lockdown would be taking place, the agent and I agreed we'd communicate once travelling is permitted. Since the lockdown came to level 1 and traveling restrictions have been eased, I've been sending emails to no avail. Their phone is not going through, there's a voice promoter that tells you to leave an email and an agent will get back to you. Since lockdown level 1 I've been waiting and sending emails but no one has gotten back to me. Why arent they communicating?
