After 1.5 years, Telkom get busted!

Good day,<br> <br> I have been a client of Telkom for a year and a half now using their 4mb ADSL and I have been calling their call center on a daily basis (this is no joke) due to high ping rates and slow internet connection in my gaming sessions. They repeatedly claimed it was my lines fault, so 4 technicians over this entire period came out and none of them were able to resolve the issue. They just closed the cases and ****ed off. The fifth technician that was in contact with me brought everything to light however. He was working on my line from the exchange side and said that Telkom had put me on a 3mb port/cap from the exchange instead of a 4mb line. I have been paying for a 4mb line the entire time! He even went through the detail of showing me this info on his gadgets and on my router. I have been paying a year and a half for a service I have not been able to use it once without pings of 100ms or more in game. I have over 50 reference numbers and multiple escalation numbers and even a hellopeter reference. Not once did they admit fault. I want a refund from Telkom for the entire period of being charged for something I did NOT receive!
