Indignant service by Blue Label Connect

I have been battling for years on end to get my sim card to it's original state( PREPAID) since it was changed from prepaid to a contract sim, I now need to do a sim swap, I can't get help from my service provider Cellc, I have called Blue label connect, I was placed on hold for over half an hour, then my call was cut, since then every attempt to get through their call center has been a nightmare, all emails that I was provided with, are not valid. Do they even know the importance of a cell number , as it is literally connected to so many things. To think that I was ******* into this new arrangement is the worst nightmare, I was asked by a Jet consultant if I needed airtime with my purchase, little did I know that , my prepaid sim would be swapped for a contract sim
