Disappointed Vodacom Customer

Last year I received a call from 082 number unfortunately they were trying to do a sim swap on my number. I called Vodacom to report this and the 1st agent I spoke to didn't reverse the sim swap instead he refreshed the network connection. I had to call again to be assisted by another agent which was unnecessary for me to call again. Beginning of the month I lost my phone, I called the call center and was advised that my number is flagged - no reasons provided for this. I was advised to go to the store. I've been going back and forth to the store at the Mall - Jabulani Mall till today I haven't been able to get my number cause they either offline or they don't have blank sim cards and they show no care none what's so ever and their service sucks big time. Why is my number flagged, I can't access my apps and I use my banking app. Vodacom had put my life on hold for a month now. I'm frustrated don't know what to do.
