Kulula need to answer their phones!!!

I've been trying for almost a week and made 18nphonecalls at various times of the day. No one answers the phone. Whether it's at the early start of the day or any other time, you get a standard response - We are experiencing high call volumes and your call is important to us!!! If the call is important to uou, Kulula, then make the necessary arrangements to have the phones answered!!! I have a covid query which cannot be answered via the website Service?? What service?? It doesn't exist!!!
