TERRIBLE INTERNET SERVICE FROM TELKOM

I have been with telkom for on 6 years. a landline as well as uncapped wifi. I have had nothing but problems with my wifi. i changed from a 4mgb speed to a 10. even worse. I recently changed my fixed line to an LTE line, as I was told this should solve my problem. my problem is not solved, I am so frustrated. my internet goes on and off intermittently. I pay R800pm for a service that is not satisfying me at all. we log calls, they get esculated, but the problem is not solved. I Do not know if they are throttling my service, or what they are doing. I AM TOTALLY FRUSTRATED.
