Tired of being sent from pillar to post from Sales department and Business technical support, looks like they are not clear on their roles!..

Today I called to be assisted to choose the correct menu option to block outgoings from our office line (from *35#). We need to be able to make outgoing calls to Telkom landlines and Telkom Mobile cellular numbers only. I spoke to a total of 6 people between Telkom Sales and Business technical support and have had no joy from neither department; I sensed a lot of reluctance to help because none of the departments accounted for this kind of request. They kept on point fingers at one another, so who/what should I believe?! They will make you believe they are assisting you while you hold the line, only to find out that you are being sent back to the main menu... Ultimately, after 1 long hour, I spoke to the very last agent in the Sales department whose name is Adrian. He also gave me the same story to say I need to speak to the technical support department, so I asked to speak to one of the supervisors because I was beginning to get annoyed and irritated from the backs and forths I experienced. He told me that 3 of the supervisors had stepped out and only one was available however couldn’t attend to me as he/she was busy with another client. I truly fail to understand how it is possible for all supervisors to step out at the same time while this is a busy call center?! So in my mind I concluded he was not willing to refer my query to someone that he knows can assist or direct me to the right person that will assist. Adrian is very rude; I wish I had recorded the call as proof. He does not know his boundaries with clients very well and needs to polish his people s****s. The least he could have done was to arrange for someone (meaning a supervisor or senior) to call me back and see how they can assist me seeing I was frustrated from this unpleasant experience. He failed decimally to do so, instead we ended up quarreling and insulting one another. It is for this reason I decided to escalate this matter to hellopeter since I'm not getting joy from my service provider. The request is very simple and no one wants to account for it, so who can assist me if they can’t nor direct my call correctly?!
