Neotel has again erroneously suspended our phones

We have had Neotel phone lines for the last six months. Every month our phone lines have been suspended. We are told that it is due to our lines being capped. Every month we are told that the phone limit will be increased and that the phone lines will not be capped again. Every month it happens again, even though we have not reached our limit. In turn our internet access is stopped, even though we have uncapped internet access. This is besides the fact that the sound quality on all calls is pathetic. We are a law firm who requires our phone lines for both incoming and outgoing calls, and the internet to do all our work. The down time on the phones affects us for at least two to three days a month, which further results in massive losses to our company, and we would like to cancel our contract with Neotel as a result and not be liable for the full two year contract. Further to this, when we contact a number of people who have sold us the line and have assisted us to sort out the problem previously, all of these people advise that they no longer work for Neotel and are unable to assist us. These people are Tshepo Mpebe, Craig Schelin and Carl Schelin.
