Back response from Afrihost to technical issues.

We are a small ISP hosting about 80 company's websites and email accounts. Since early morning Friday the 18th May none of our web sites or email have been accessible on the Internet due to technical issues at Afrihost. It has been impossible to contact Afrihost support by telephone. In spite of us sending email messages and using their WhatsApp platform and requesting a call backs via their Client Zone web page we have been unable to get any meaningful response from them as to when the system will be up again. As of now (13:18 on Saturday 19th May) we have been waiting 2 Hours for a call back. Are they trying to put us out of business?
