Bad Customer service when trying to do Sim Swap

Hello Peter <br> On Friday 26 June 2015 my phone got lost - on the very same day I bought a new Sim card and I tried to do a Sim swap for my number. On the first attempt I got an sms notification that MTN does Sim swaps between 0800am to 18h00 I must try the following day. The following day Saturday 27 June 2015 - I tried the \Self Surviving option to do a sim swap and once I again I was referred to the Call Center - 173. I tried to contact the Call center the whole day without success as the keep telling us that they are currently busy and I was on the phone for almost the whole day. <br> I tried again on Sunday 28 June 2015 - once again I was holding patiently for almost 50 minutes and finally I got through to the call centre and I spoke to consultant by the name of Lucretia - the consultant was very rude and was unwilling to assist me . I asked her if I can speak to her Team Leader /Manager and she refused to let me speak to the manager /Team leader and told me that they can't and she will tell them to give me a courtesy call and I am wondering where are they going to give me this 'courtesy call"as she did not do the sim swap or take down my details."""
