Cell C unfair treatment for prepaid customer

I am so disappointed with Cell c, bought a new sim card a month ago at Pep i also Rica it at pep, 2weeks later sim card just decided to stop working when i called in at cell c customer service i was told that the sim card is faulty i must do a sim swope at Cell c store. That time the sim card is loaded with a R50 airtime and 4 GB data that is expiring in 7 days. I went to Cell c Savannah Mall on 06 August 2023 i was told that there is no simcard for prepaid customers only contract i must come back during the week , i called today before i went there cause last week it was a total waste of my taxi fare i didn't want to waste my money i was told that we are offline we can't help go somewhere else . During all this i lost 4GB of my data , my Question is why does Cell C still have branches if they can't help, 2 weeks my friends and family can't reach me for something that not even my fault. Where is customer service? Do cell c only care for contract users ?
