RICA SIM AFTER SO MANY YEARS!!!!

On the 13th of November 2020, I was registered on a contract with a company called Blu Label Contact. They are giving free airtime for 3 months. I have never registered for any contracts and was put onto this company without my consent. I was not aware of this until my incoming call identity was blocked. Every call I received was coming in as "unknown". I called Vodacom to enquire and I was told that I am on contract. They then transferred me to Blu Label Contact, where I requested that they change it back to prepaid. 3 Days later and it had not been done. Today I called and spoke to Michael at Blu Label Contact, he advised it was a network error, hence the delay in changing back to prepaid. Not longer after the manager called me and advised it has been done. Now that I am back to Vodacom Prepaid, I get an sms that I need to rica my sim card. I have had this number for years and now Vodacom is requesting that I take time out of my busy day to rica my sim. Due to the fact that it was changed from contract to prepaid. I never opted for a contract in the first place. This was done without my permission. I am sadly disappointed that individuals details are being registered for contracts without their permission. How did Blu Label contact get my details in the first place?????
