AFRIHOST : LACK OF RESPONSE

Our internet connection went off this morning at 10:00. It is now 13 hours later. We have sent emails and whattsapps - no response whatsoever. For people working from home, it is critical to have wifi - our livelihoods depend on it and this lack of client service is just unacceptable - there is no person to talk to and on their online client support system, their agents are not working at the moment. How do you get in touch with a company that does not respond?
