MWEB Is our ISP and also the DSL line provider. In June 2015 we decided to upgrade to a 10Mbps DSL connection, after confirming availability with MWEB and Telkom. Ever since the upgrade our realtime download speed varied between 3-4 Mbps (slower than when we were on 4Mbps!), I reported this to MWEB on various occations, and we did various tests until we finally determined that it is a Telkom DSL exchange problem. MWEB then opened a fault with TELKOM. It is now October, and we still had the slow performance. Since last week Thursday we had NO connectivity, the DSL connection has been down since then. We are on day 5 with NO internet connectivity. Every time I phone MWEB the standard reply is that it has been escalated with Telkom management. MWEB has been great in phoning me every day, but every time I have to listen to the same response \It has been escalated with Telkom"....but still no solution! What must I do next? I even reported the problem directly with Telkom"
