Unable to do SIM Swap at Vodacom on my own number and I need a Letter coming from you

Hi Blue Label Connect

Please note that my cell phone number 072....... was placed on a contract with Vodacom without my concern and knowledge, therefore I am now unable to do a SIM Swap, Vodacom requires a Letter or Letter Head coming from your Institutions with JET Store to allow me to make a SIM Swap on my own Number.?

May you please send me that Letter and And also CANCEL this Contract as I did NOT ask for a contract with Vodacom.

Please Assist me as I need an authority on my own Number, I cannot be told I cannot do anything on my own Number. It used to be Pre-paid and suddenly it is a Contract which I am unable to do anything about it.
