Unauthorized inconvenience on my number

This company Authorized a contract and changed my price plan to "U choose 65" without my authorization, called them 02/01/2020 to cancel this inconvenience on my number as I am unable to do Sim swap without their authorization and they promised me to cancel everything within 48 hours but nothing was done.
