BAD ETHICS

On the 10/12/2015 i received my Dec/Jan bill. I noticed that Telkom charged us double for the following, Dsl Faster from 10Nov to the 8 Dec and Telkom Evening W/ ender 10 Nov to 8 Dec. Thinking that this is right they added all of this to my Dec/ Jan bill. Concerned i phoned in to be told that they will log a dispute for double payment. No one got back to me, i called in to find out the progress of my dispute and was told that it was closed because it was not a double payment they are charging me because i only paid 288 in November reason being we had limited internet services...from 4mbps we were getting roughly 1.38 mbps. So much for credit for limited services..you could have left the whole credit story and charged as per normal as this is what you have clearly done. I as a customer will not pay for the Nov charges added on my bill as we are not getting what we are paying for. Please sort this dispute out as this is bad ethics, calling in just to find out progress of disputes is a mission being put on hold for 20 min..till i hangup..i say thats passing the buck, dipute id ***9. This issue needs to be addressed please. To the young man Sininthemba who tried to help. Thankyou.
