No Service

I recently had to do a SIM swop with MTN as a result of buying a new phone. I was told in store on 10 April @ 18:00 that my SIM swop can take up to a maximum of 24 hours (which is already unacceptable as Vodacom SIM swops take 2 hours). Today, 11 April @ 13:00 I phoned MTN again (18 hours after the SIM swop) to enquire on the status as the SIM was not yet working. I was told that they will escalate and to be patient and wait 24 hours and then phone again. So I phoned now on 11 April @ 19:30 (25,5 hours after the SIM swop) and I was told that they can see that the SIM swop has not yet been processed and that it can take up to 3 days and that there is nothing else they can do. 3 DAYS!!!! Are you people serious??? How am I supposed to be accepting that??? Can someone from MTN that work's with SIM swops just phone me and get this sorted?
