Terrible Customer Service at Cell C Four Ways Mall

I have been with Cell C for the past 2 years with no complaint, so when my contract was due for a renewal I was more than happy to. I received my new phone LG K40 and I was happy. For me to be able to put the sim card to my new phone I had to open the sim card plate with a pin and I was struggling to open. Not wanting to damage my new cellphone I went to cell c four ways mall and I was assisted by a consultant named Londiwe. Firstly Londiwe looked at me like I was stupid for even wanting such assistant and angrily opened the sim card plate and broke it and walked away leaving me standing there at reception. I called her back and showed her what she had done and her response was, so who's problem is it now that your phone is broken, my heart sank, after a long argument between me and this consultant I was now in tears because she kept on insulting me telling me that I'm exaggerating things. One of the other consultants sat me down and tried to assist me, unfortunately they didn't have stock of the specific handset so they couldn't replace my sim card plate. The manger of the store eventually arrived after what 20 minutes, she didn't introduce herself to me, didn't apologize on behalf of the consultant who was now giving me looks and she just spoke to the consultant who was now assisting me, he promised me that I will have my sim card plate between 5-7 working days, that was the 13th of December 2019 and I still haven't heard from the manager or the consultant. I can't send voice notes on my phone and even when I receive voice notes they are never clear, I don't know what she broke inside my phone when she was opening it.
