Not fixing Internet line speed and ping

My Internet and Telephone service was cut-off on 16/01/2016. My wife reported the loss of service to Telkom on 18/01/2016 and received a reference number 70CTK280116. Our service was not restored within Telkom's 5 working day turn-around time. We had to call Telkom repeatedly during the next two weeks to get feedback and progress updates. The service-desk staff is unable to give valuable progress updates and repeat the same nonsensical information. The fault needed to be escalated (817118) in-order to receive attention. Our service was only restored 3 weeks later (20 workdays past turn-around time) on 07/02/2016, but I noticed line-speed issues. The technician called to inquire if everything was working, I complained that the upload line-speed was half and the ping was at least 20 ms higher than before the loss of service, but he didn't heed my complaints. I promptly reported the issues to Telkom on 08/02/2016 and requested that the job card should not be closed, but they closed it anyway. Since then I've called Telkom several times, but the service-desk staff just keep promising that I'll receive a call from a Telkom representative. It's now 25 workdays past turn-around time!
