Poor swervice

I would like to lay a formal complaint regarding the service I received from Rudolph in Centurion Mall. I explained to Rudolph that I would like to do a SIM swap for my prepaid SIM card and Rudolph advised that my Cell number is not registered with Vodacom. I explained that I have been with Vodacom for the past 10 years and Rudolphs solution was go to another network provider to confirm that I have not ported my number, I then asked him to try another PC/system to see if maybe its not a system error and then he referred me to different vodacom store which I complained about the distance and time. I asked to also do a contract application and instead of proceeding with checking if I qualify, Rudolph requested that I take the documents he asked me to complete with me. In short Rudolph was not willing to assist me with my SIM swap request and my contract application moreover Rudolph was very rude to me.
