Poor service, *********** staff- I urgently need assistance

I'm at my wits end with Telkom and their *********** employees, contact numbers that don't work and poor service overall. I went to the Telkom branch in Centurion in March 2018 to have my line moved to my new address, during the first week of April 2018 a technician came out to install my new Telkom and ADSL line, I was using a 4mb line at the time and a consultant called me and offered me an upgrade to a 10mb line, I accepted and was told that the new line will be installed when the technician comes to install the line at my new address, after the installation is done, the technician says he can't upgrade the line because he was not informed about this and I must call the call center. I call the call center every afternoon for over a week firstly holding to speak to a consultant for over an hour everyday, when I finally get to speak to a consultant, they tell me theirs nothing they can do, I must go to the store. On the 12/04/2018- I go to the store in Centurion, I get told "No Mam, we can't help you, you must call the call center" - I refused to leave the store till someone assisted me, Its already been over way too long that I was trying to get assistance. They logged a call and I was contacted by the call center, A complaint was logged ***, the consultant tells me I will be contactedno later than Monday 16/04/2018 for the new line to be installed. On the 13/04/2018 I received a text message informing me that my fault logged was restored and if the problem still persist I must contact the call center. I called them once-again and this time I am told that my upgrade was successful from a 4mb to a 10mb but my line speed is still set on a 4mb and theirs nothing that they can do and I must call the Sales Call Center on 10213 during office hours, Seeing that I don't have a Telkom line at work, I search to find a number so that I can call this Sales call center on, I call ***They tell me they cant help me and I must call the sales call center, They are not able to provide me with any contact number other than the numbers that you call from your Telkom line, So my work hours are from 7am ranging to 16:30, 17:00, 18:00 - I can never get home early enough unless I take the day off and sit at home next to my Telkom line to call this damn sales call center. I am so frustrated, Telkom sales consultants called me profusely when they wanted my business, when I was busy and could not answer, they would even call back, after I accept the upgrade, you don't hear a damn thing back, they count not even complete the order and make sure that a technician is appointed and of course the 10mb speed that I have not been able to use as yet is already on the Invoice. I spoke to a Telkom business consultant yesterday and she said she will load a message for someone to call me back- still waiting. -I don't even know why I am still a client at Telkom, Their service is pathetic, Their employees don't know anything. I have been paying over R800 for over 3years and have never gotten over 2mb of internet speed. whenever I called them about that, they would say peak hour or some ******* - The internet is super slow just like the service provider. I want someone to assist me, I am seriously considering finding a new Internet service provider. I'm currently paying around R1000.00, if Telkom is happy to lose my business, I will gladly start searching for a New Internet service provider where I will probably get a cheaper monthly rate for faster better Internet speed and competent service delivery as well!
