Very poor Telkom service

I logged a fault with Telkom on 15 Dec 2017 as there was noise on my ADSL line and internet speed was intermittent. Despite many follow up calls and promises that a technician will be in touch, I now have no voice line at all and 0.75mbps speed on a 10mbps line. Pathetic service by Telkom, I am now considering other providers and will be terminating my month-to-month contract shortly.
