SIM SWAP DISTASTER ***

I went to do a sim swap at VODACOM STORE IN BROOKLYN and i was told i must switch on my phone after 4 hours . Switched it on the next morning and the sim keeps stating NOT REGISTERED. I contacted the call center and spoke to nomvula and she told me nothing was done on my sim and i need to go back to the store. I asked her to do it on her side and after giving her the sim number she tells me MY SIM DOES NOT EXIST!!!!!!!!!!!!! LIKE WHAT MUST I DO WITH A SIM I GOT STRAIGHT AT YOUR STORE & YOU TELL ME IT DOES NOT EXIST?????? THIS IS NONESENSE!!!!!!! NOW I MUST GO BACK TO BROOKLYN AGAIN. Someone better contact me TODAY. My alternative number is ********** !!!!!!!! YOUR SERVICE IS THE WORST!!!!!!!!!!!!!
