DISASTROUS CUSTOMER SERVICE AND VOIP SERVICE

I have tirelessly reported my VOIP service not working via whatsapp as their service request is always not available online. each time I have to explain to an agent but nothing has been done for some time. No voice calls can be made most of the time and having constant issues with connection. fault has been reported but no feedback or resolution from Webafrica. I have been their customer for 2 years but it seems their customer service has just gone downhill recently. I will be also cancelling my fibre 200/175 mbps and join another ISP.
