Porting

I've been trying to Port to MTN since on the 15/03/2020 at 10h00. I followed all porting Instructions from the starter pack, things like, buying a new sim card and Rica it the sms the word portme#new sim number to MTN number. In just few minutes I am SMS to say my request is been processed. On the 16/03/2020 around 17h00 I received an SMS to say "my port request has been approved and is ready for Port activation." Today is the 17/03/2020 time 11h40 I'm still on my current network no porting has taken place I emailed customer care to enquire how it take to port, their response is that it take 2-24hours, but as for me is more than 24hours. If I was porting to Vodacom or Telkom by now I would've been ported without any hassles Maybe MTN have over flowing customers, they don't have a room accommodate new customers.
