4 Hours on hold

I have been trying to get a hold of somebody in the Porting Department since this morning. My 1st call i held on for 1h16 mins then decided i will call back later. I called again at 2pm and carried my spare all around with me and held on for a further 3 hours and to my surprise still no answer. I have the proof as per a screen shot of the call. I have been given the number by the MTN callm center to call ***. My first call to MTN 173 I managed to speak to a supervisor who said she will be able to assist with my query but then our call got disconnected, then i called back, spoke to another agent who refused to put me through to a supervisor and said i should contact *** who will be able to assist me. <br> <br> I am now at a dead end as i have wasted 4 hours of my day holding on for somebody to assist but the calls are not even been answered. <br> <br> I would like somebody to get in contact with me urgently as per my listed phone number
