Pathetic, process. how long must i wait

Upon successfully upgrading to the iphone 6 i needed another mtn contract. completing the new contract request. I was approved within 2 hours of completing the forms for another iphone 6 128 gig. i requested to have my vodacom prepaid number ported to the new contract they said that this would not be a problem. i got asked to come back the next day to complete the port process as their system would crash upon trying to complete the port process. i went back the next day. they tried to port my number and explained to me that they had not yet put in the request to port and it would take about 2 hours to request and get the request approved. to which they could port my number. they explained it WILL NOT take longer than 48 hours to which they guaranteed me i could get my phone. 4 days passed and my vodacom sim had not lost signal like they said it would in a 48 hour period. So i went to mtn AGAIN. he explained to me that the port has been done but the number has not been vetted. He tried phoning and emailing to sort this out promised me that the problem would be sorted out by monday evening and it boils down to people not doing their job 48 hours later im still waiting!!
