Unfriendly, Unhelpful consultant

<br> I lost my phone on the 06-02-15 and bought a new phone with a mtn sim card yesterday, since morning I've been trying to do a sim swap with no success instead I've been given a round around. The consultants asked me security questions,ie when last did I recharge and how much, frequent numbers that I call. I gave them all this information but still its not enough, they are now asking me what service do I have on my number, voicemail lite and staff. I am so angry and disappointed with this network more especially your consultants who are so rude, rude its actually a understatement. I am frustrated by the fact that my business is suffering as clients cant get hold of me on the other hand I am not getting any help from MTN HELL, Can a manager or superviser kindly assist in this and word of advice your call centre staff really need some customer care training.
