Bad Communication / Attitude Service

I am disgusted with the services I received at Cell C Parow Centre on Monday, 09 August 2021. I went there to get a sim swap, they advised me that I need a proof of address and ID, I made all the effort to get the proof of address just to get there again and them telling me with a don't care attitude that I need a bank statement... bare in mind at this point i was frustrated because why did they not inform me why i need a bank statement to rica a sim card. Their attitude was asif they were the boss and I just have to follow what they say.

Also the guy's attitude was so bad he didn't even give me a chance to ask why I needed a bank statement to rica a sim card (as I was so confused). He was just like you need a bank statement when I tried asking why, and when I left the store I heard him and his colleague laughing.

Is this the type of customer service Cell C provide to their customers?
