Sim swap horror

I lost my phone on Saturday and blocked the phone and sim. Now I have been struggling for a sim swap. I went to the vodacom shop in midrand with my ID and proof of residence, sat there for an hour only to be told there is a problem with their system and they cannot help me. I have had a contract with this **** company for years and now I can’t even get a sim swap. I have been calling them everyday and everyday it’s a different story. Yesterday I was told that I have to wait 24 hours and now that has changed. I cannot do anything as all my accounts are linked to that number, my internet banking most importantly. I spoke to the team leader at their call center who flat out told me she won’t help me, she just sounded like a programmed machine who didn’t even listen to what I had to say, at this point I just want to cancel this stupid contract and move on with my life
