Disgraceful company!

I'm so sick and tired of Telkom and some of their useless service and staff at the call centers. Can you imagine that I have not been able to sort out a simple query for 2 weeks. Simply because I keep being told to call another department. I first called sales on 10213, explained my query, the consultant said I must phone technical, I phone technical, they say they are unable to pick up such information I must call 10210, I call them they say I must call sales, I told them I did, they say I must phone them, I call sales again and get told I must call 10210??? Who can believe this nonsense??? I can't believe that such a big company as this has such *********** staff on their payroll. Now it's 2 weeks down the line and my query is still not solved. What am I supposed to do? Who must I phone then? Is there another department I can phone who can actually assist me?? This is beyond rediculous, it's not even funny anymore. What is a person to do?? And the saddest thing of all is that the query I'm trying to solve is a problem that they actually created themselves!! I received an sms that's confirming the cancellation of my line and services, but I didn't cancel anything, there was a TIN I was still being billed for but no line connection to it, another fault of Telkoms I might add, and it was supposed to be cancelled but Telkom did actually call me and cancelled it while I was on the phone with them, other than that I have 2 lines and I'm using both lines, I never cancelled anything, so I'm trying to get hold of any department who deals with this to find out what the hell is going on, and low and behold it just so happens no telkom department deals with such things. But I can tell you one thing, if any of my lines gets cancelled and I'm saying this again, I did not request any of my 2 lines to be cancelled, because I received the sms and immediately called, and have been calling on a daily basis, and nobody can assist me because everyone keeps saying I must call 10210,or sales, or technical. Absolutely no department has helped me this, because they keep passing the bucket.
