Poor Network & Terrible Service

We need this matter to be escalated please. We used to have an LTE line which we had numerous issues with. We switched to ADSL a month ago and this has not worked properly for a single day since we connected. We have now been billed R1200 for WiFi for that does not work! We can’t even do a speed test even though it’s shows full signal. Fed up with poor service, terrible network, bills and having to fork out for data because our WiFi never works! We can’t even cancel because we have a contract and will then need to pay In the difference . We need a solution please !
