PORTING NIGHTMARE

I am having serious meld down issues with Telkom. I ported my number from MTN to Telkom on the 12/08/2019 at 10:19 am, on 13/08/2019 I received a confirmation sms from Telkom stating the port should be complete in 24hrs, and I also received an sms from MTN stating I am off their network. It is now the 15/08/2019 and I CANT USE MY PHONE!!. The new Telkom sim which was ported with my MTN number is in my phone but it keeps saying insert sim card and not registered on network. I have phoned Telkom numerous amount of times but no one seems to be able to assist me. I have even loaded Data and airtime as per the Telkom call center suggested but nothing. There is no Telkom store in my area and I need my phone to work TODAY!!! Case number at Telkom is ***5. if anyone that has a clue what to do can call me on *** because this is ridiculous!!
