Bad service

I went to cell c Menlyn shop to do sim swap I asked for the manager so I can get my sim swap sorted, he came and checked if my number is still active and said I must write down the numbers that I frequently used to call, I did write down the numbers when I was done I was made to wait for 30 minutes. I finally asked for helped from the consultant who was just siting and doing nothing, the same consultant with a lot of attitude told me she can’t help me with my sim swap because i have a long list of number that I wrote down, I overheard her telling the guy she was with that she won’t check that list because it’s too long and it will waste her time. I have been using this number for more that 10 years and I still need this number,
