Poor Poor Customer Service !!!!!!

I reported/logged a call with Telkom 6/7 weeks ago *** in regards to my LTE internet speed only averaging 0.3 Mbps d/l and 0.21 Mbps u/load , a technician was deployed to my house in the 2nd week on August to do test. To date i still have not received any feedback regarding my call status, called the call centre who were not helpful instead will put you on hold for more than 20 min without anything tangible coming from them. This incompetence is affecting my work and pockets ,I would like a more detailed explanation or timeline expected for this issue to be sorted out.
