ABSOLUTE PATHETIC NON-EXISTENT SERVICE FROM TELKOM

I upgraded to Telkom's 4gig UNCAPPPED earlier this year and since then my internet connection at home as been non-existent and even slower than what it was before. i upgraded for a reason so my adsl can be faster and it has NOT been faster - it has been slower and in certain areas in my house non-existent. I have repeatedly reported this by logging a fault and NOTHING is ever done. I don't even receive an sms confirming my report of the fualt (i reported it again this past week - (ref. ********** 0) i never received an sms or any feed back as usual and i am SICK AND TIRED OF THIS PATHETIC USELESS SERVICE. I am having to use my 4G/mobile data as my adsl is NEVER stable. THIS IS UNACEPTABLE! I AM CANCELLING MY TELKOM ACCOUNT AND I WILL NOT BE PAYING MY ACCOUNT FOR DECEMBER 2017 (R1024.55) WHY SHOULD I PAY FOR A SERVICE THAT IS NOT WORKING..??? I AM FED UP WITH TELKOM AND THEIR PATHETIC SERVICE. NO BODY EVER GETS BACK TO ME OR ACTUALLY DOES SOMETHING TO RESOLVE THE PROBLEM. I HAVE HAD ENOUGH!
