Terrible service from Vodacom

I installed VOIP and Internet at my dental practice in March this year. Since then the service has been down on numerous occasions and we reported it to no avail. This has continued and worsened so much that it is down for the last 3 weeks. We have reported it several times every day. Vodacom promise to send technicians to no avail. A person by the name of Mpho promises to revert back to us and when we call again he is either not available or on lunch. This is unacceptable because patients with pain are unable to contact us. I also have other business contracts with Vodacom and will have to find another service provider since their service is extremely poor. TERRIBLE SERVICE!!!
