Adsl Data package problems

So frustrated with Telkom's internet service since line was installed calls have been logged 1st it was speed which was increased continuous calls were logged to refresh line or for technician to come out ... some call centre agents pick up a fault other not fault found. Unlimited data bundle 10mbps signal always dropping ... then latest response was line throttled but we are hardly at home ... waited for new month to kick in same thing .... taught it would be a benefit having unlimited data bundles but what is the use paying for a services that you not happy with because internet/ Wi-Fi always buffing and no one from Telkom can assist ...
