Telkom the worce service provider in SA

What can you say more about Telkom from the best to the worce. Migrating from ADSL to LTE on Telkoms instructions I cannot dail more than 40% of the numbers due to routing and database issues on Telkoms network, my internet speed has gone from the slow ADSL crawl to NO service the most of the time or to Morse code when up, reporting it over and over and over at their customar SCARE is like speaking to a brick!
