*********** call centre agents and team leader

On the 3/10 I received my statement from Telkom mobile which was unusually high I immediately called the contact centre to find out what exactly is happening on my account. I was then told a case would be logged to investigate the cause .I then called on the 4/10 to enquire about the status of the log and I was told that it would take 3 working days. Then I called on the 6/10 to follow up on the log spoke to Smangele Ngcobo who then advised my log has not been touched at all. I then requested to speak to a manger but she advise me their is no managers available and my query would only be dealt with on Monday. I insisted to speak to some type of superior to take responsibility of my query so that the next time I call I would be able to get some constructive feedback she put me on hold for 17 mins and dropped the call. I called back from the same phone and was automatically put on hold I then called from my wife's phone and some one picked up immediately before my call. huh? I then requested to speak to team leader(Tenjiwe Nhlapo) who failed Telkom miserably I cannot believe she is a leader in a call center. she did not assist at all and could not take responsibility for the log...
