Redistribution of cellphone numbers

About a year ago, my cellphone was ****** along with the sim card, I called Vodacom to report it and get the itc number to open a case. I was told that the account was in arrears and I needed to pay R1100 plus buy a new sim card that cost R105 of which I comp****, but to my dismay my number was not reactive and I was told that I needed to pay another R1800, of which that was not the initial agreement, I was also told that I had done an upgrade and that the payment was increasing and I needed to pay a minimum of R600 per month of which I refused, that's when they began to request bank statements and proof of employment, I was told that until I paid off the account they would block the number But this morning I saw that the WhatsApp had been active and the profile picture that I had on the number had changed to an older woman , to my dismay they recycled the number despite not wanting to investigate and forcing me to make payments that I could not afford
