Appalling service

I am really disappointed in how Telkom runs business. On or about September 2017 I took a contract with Telkom for two Sim cards. when I received my first bill I noticed there was a number I do not know on my account. I called in on the 22 Nov to gain clarity and the conclusion was I had to fill out a cancellation form. I did so and sent it back to them. Long story short, after a lot of up and down with the call center agents (who really need training on how to categories queries), in April 2018 (after following up yet again myself) I discovered that I was ill advised by at least 3 call center agents, and the one person who said they would log my case did not log it. On the 13 of April 2018 my case was actually log and I had hope that my case would be resolved with much haste. To my disappointment 13 working days later (despite their turn around time on a case being 3 working days) my case is still not resolved. I have been patient, I have assisted them with all the information they needed, I have conducted the investigation for them and sent them an email to show them what information I have obtained on my side however Telkom has still failed to act on a simple matter such as incorrect invoicing. Despite the incompetence I have faced my biggest issue is that not even a single person from Telkom have called to update me on the matter, whether we were in the ill advised cancellation phase of the matter or the ********** case that is "being investigated" stage. From my 1st submission on the 22 Nov 2017 until the 04 May 2018 Telkom has not cared enough to pick up a phone to inform their client on the progress of a matter. This is truly the most disappointing element in this whole matter. With my disappointment I wouldn't even give them the one star I'm obliged to here.
