Sim car locked a few days after porting to them - regret joining them.

I ported my number to Telkom Mobile about two weeks ago. Everything went fine after I have ported and I could use my number and even loaded airtime. Then out of the blue on Monday 12th July my sim card wuldn't work. Just a few days after I ported to Telkom and I had lost my number. When I tried to use my number it gave an error that it was locked. Nobody informed me of anything prior to the number being locked. I then contacted Telkom to be told that in order to have the phone unlocked I have to go to a branch. Guess what? Their branches are closed due to the unrest. Now I am stuck as I can't use my phone and I am missing important communication.

Surely due to the current situation they could make some allowance to help their clients over the phone since the branches are closed. I'm approaching the second week without a phone.

I regret ever porting, I can't wait to port out as soon as I am allowed. This is ******* service. How do you lock a sim card without advising the client at such a time when communication is needed due to current sistuation?
