PATHETIC Telkom LTE service

I have a Telkom LTE wireless device and reside in Midstream Centurion/Midrand. The service is absolutely PATHETIC and very slow. There is no way to escalate my issue and what I pay and what I get for that amount is nothing but **************** I demand to have it sorted out or I need to get out of the agreement as Telkom is not providing what I pay for. I am going to cancel my payments to Tekom until this is resolved
