Move into the fast lane with Telkom LTE 1Mbps Speed, really??

I have recently done an upgrade on one of my data packages and increased the data allocation as well. My experience with the network in general has never been awesome however it has been usable. Currently I cannot use the service as I am experiencing speeds of less than 1Mbps, I have called in and received a set of settings which I used to update my router but with no luck. I have tried moving the router to different locations within my house but still no joy, I have tried everything even a different router however my Vodacom data package works fine in the router, so I have confidently established that it is not my hardware or the positioning of the router or the settings, I called in to report the fault, and to my surprise I was treated like some kind of idiot that does not know technology although I explained everything upfront to the consultant, and clearly this person was just following instructions on a pc screen and repeating them to me whereas I actually physically dealt with the matter. Unfortunately the staff member was extremely rude and raised her voice a few times, and that is where I drew the line, I made her understand that I am a customer and that I would not be on the phone with her if there wasn't a real problem. She eventually agreed to log a call and proceeded to give me a case number, (***5) I received this on 13 Nov and was told I will be contacted within 48-72 hours, surprise surprise, I am still waiting today is the 19th, I even tried making contact on the facebook page however there you get completely ignored. Why is it so difficult to just provide me with the service I am paying for, I am in a fully covered network area but not even able to make use of the service,, so tell me Telkom what am I paying for??
