Sim swap

I went into a Vodacom store this morning to do a SIM swap. I was told I could not do this and was advised I could not do this and was told the number was deleted. This number is linked to a lot of apps as well as my banking app, which i am locked out of. The person showed no interest and did not show any kind of assistance. I am utterly disgusted with this. Last year a different number I had a sim swap was done without my knowledge.
